Description

  The present invention relates to a gaming machine such as a pachinko machine.

  As a kind of gaming machine, a pachinko gaming machine, a slot machine, and the like are known. These gaming machines include a control board (control device) on which electronic components such as a CPU (central processing unit) and a ROM storing a control program related to the game are mounted, and a series of games can be performed by the control board. It is controlled.

In this type of gaming machine, for the purpose of obtaining illegal profits, the control board is illegally removed and the ROM of the board (if the CPU or ROM is integrated into one chip)
Many illegal actions against the control board have been reported, such as changing the game content by changing the game, or inputting an illegal electrical signal from the outside to the control board via lead wires etc. It is being considered. For example, fraud countermeasures are adopted such that the substrate box has a sealing structure (so-called caulking structure), and when the substrate box is opened, an unsealing history (opening trace) due to destruction or the like remains. Reference 1).

  In general, a substrate box having a sealing structure is provided in a box base that accommodates a control board, a box cover that closes an opening of the box base, a base-side connecting portion provided in the box base, and a box cover. And a cover side connecting portion. Then, when the box base and the box cover are assembled, the locking recess formed in the base side connecting portion and the locking hole formed in the cover side connecting portion are aligned and locked via the locking hole. The box base and the box cover are connected to each other by inserting a crimped member such as a pin with a bar, a broken screw, a one-way screw or the like into the recess. The breaking screw is a special screw that can be removed after screwing a portion where a tool engaging portion (cross groove or the like) to which a tool such as a driver is engaged is formed. A one-way screw is a tool engaging part that is engaged in the tightening direction (screwing direction) of a tool such as a screwdriver on the screw head, and the tool such as a screwdriver is rotated in the direction of loosening the screw. If it is, it is a special screw that cannot be removed when the tool is idle.

  Therefore, the caulking member inserted into the locking hole and the locking recess cannot be removed unless at least one of the base side connecting portion and the cover side connecting portion is broken (removed). That is, when the substrate box is opened, a predetermined mark is formed on the substrate box, so that if the substrate box is tampered with, it can be detected early and easily.

JP 2003-180917 A

  However, two board boxes having the above-mentioned configuration are prepared, and one of the board boxes is opened by breaking the cover side connecting portion, and the other board box is connected to the base side. When the substrate box is opened by destroying the portion, a box base and a box cover that are intact (no trace of opening) can be obtained.

  For example, an intact box cover can be easily obtained by destroying the base side connecting portion and removing the head portion of the caulking member from the cover side connecting portion. On the other hand, regarding the acquisition of the box base, even when a broken screw or a one-way screw is used as a caulking member, the cover side connecting portion is broken, etc. If it is pinched with a tool and turned, it can be removed. When a return pin or the like is used, it can be easily pulled out as long as a part thereof can be clamped by a tool such as a pliers. In this way, an intact box base and box cover with the caulking member removed can be obtained from the two substrate boxes.

  When an illegal act such as storing an illegal control board in the box base and the box cover obtained in this way and replacing the entire board box is performed, it is not apparent from the appearance that the control board has been replaced, It becomes very difficult to find the fraud.

  In addition, the said subject is a problem applicable not only to a pachinko machine but other game machines which have the same board | substrate box.

  The present invention has been made to solve the above-described problems and the like, and an object of the present invention is to provide a gaming machine including a board box that can leave a trace of opening more reliably.

  Hereinafter, each means suitable for solving the above-described problems will be described in terms of items. In addition, the effect etc. peculiar to a corresponding means are added as needed.

Means 1. A gaming machine comprising a control board, a board box containing the control board, and sealing means for sealing the board box,
The sealing means is
When the first connecting part provided in one of the box base and the box cover constituting the board box and the second connecting part provided in the other are connected using a connecting member,
A gaming machine, wherein the connecting member is locked to the first connecting portion and the second connecting portion so as not to be extracted.

  According to the said means 1, a connection member is latched with respect to a 1st connection part and a 2nd connection part so that extraction is impossible. For this reason, in the substrate box having the configuration of the means 1 provided with the first connecting portion on the box base and the second connecting portion on the box cover, the first connecting portion on the box base side is broken to remove the substrate box. When opened, the connecting member cannot be removed from the second connecting portion unless the second connecting portion on the box cover side is destroyed, and an intact box cover cannot be obtained. Similarly, when the second connecting portion on the box cover side is broken and the substrate box is opened, the connecting member can be removed from the first connecting portion unless the first connecting portion on the box base side is broken. You can't get an intact box base. That is, even if two substrate boxes having the configuration of the present means 1 are prepared, both the box base and the box cover cannot be obtained without leaving any trace of opening. In other words, it is possible to more reliably leave a trace of opening the substrate box, and thus to suppress an illegal act such as replacement of the entire substrate box.

  The above-mentioned “control board” in the gaming machine is one of “control boards that control predetermined control relating to games”, for example, “main board (main control board)”, “payout control board”, “display control” Various control boards such as “Board” can be cited as examples. Among these, the “Main Board” that directly controls the player's profit, that is, the “main board” that controls the game value assignment (payout of prize balls, etc.) If the sealing structure is employed as a sealing structure such as a “dispensing control board”, the above-described effects are particularly effective.

  In addition, as described above, the “unable to pull out” means that the connecting member cannot be removed from the connecting portion unless the first connecting portion or the second connecting portion is destroyed. It means that the release operation of the locked state of the connecting member in the portion cannot be performed.

Mean 2. The connecting member is inserted into the first connecting part through the second connecting part,

As a result, it is possible to further enhance the above-described fraud deterrence effect.

  In addition, as described above, each holding member is “unable to be removed” means that the holding member cannot be removed from the connecting portion unless the first connecting portion or the second connecting portion is destroyed. This means that it is impossible to release the engagement state between the connecting member and the holding member at the connecting portion.

  Means 3. 3. The gaming machine according to claim 2, wherein the insertion direction of the connecting member is orthogonal to the insertion direction of at least one of the first holding member and the second holding member.

  According to the means 3, the connecting member and the holding member are controlled to be orthogonal to each other in the direction in which they are pulled out from each other, so that both of them can be more reliably removed from the connecting portion, and the above-mentioned fraudulent deterrent effect can be further improved. Can be increased.

  Means 4. The gaming machine according to claim 2 or 3, wherein the connecting member and at least one of the first holding member and the second holding member are engaged with each other so as not to be extracted.

  According to the means 4, since the engagement state of the connecting member and the holding member is more stable and cannot be reliably extracted from the connecting portion, it is possible to further enhance the effect of suppressing the fraud. As a configuration example, for example, on the first connecting portion side into which the distal end side of the connecting member is inserted, the rod-like connecting member is inserted into the hole portion of the flat plate-shaped first holding member arranged in advance, and the connecting member A configuration in which the peripheral edge of the hole of the first holding member is fitted to the constricted portion provided in the two and the both are engaged is exemplified. Moreover, in the 2nd connection part side by which the rear end side of a connection member is arrange | positioned, with respect to the constriction part provided in the rod-shaped connection member inserted previously, the flat plate shape notched in the substantially C shape Examples include a configuration in which the distal end portion of the second holding member is fitted and the both are engaged.

  Means 5. In the relationship between the connecting member and at least one of the first holding member and the second holding member, by inserting one of the connecting member or the holding member into the other, a part of the other member is deformed, The game according to means 4, wherein the connecting member and the holding member engage with each other in an unremovable manner when the portion is in a state of restricting movement of one member in the pulling direction as a locking portion. Machine.

  According to the means 5, for example, by inserting a rod-like connecting member into the hole of the flat plate-like holding member, the peripheral edge of the hole of the holding member is irreversibly deformed, and the corresponding portion becomes the locking portion (the locking claw ) And engaging with the constricted portion of the connecting member in a state in which the movement of the connecting member in the pulling-out direction is restricted. As a result, the effect of the means 4 can be further enhanced.

Means 6. The first connecting portion has an insertion hole into which the connecting member is inserted, and a first lateral hole portion provided to intersect with the inserting direction of the connecting member,
The second connecting portion has an insertion hole communicating with the insertion hole, and a second lateral hole portion provided to intersect the insertion direction of the connecting member,

  The first opportunity corresponding unit 33 includes an upper winning opening 33a and a lower winning opening 33b, and a pair of opening / closing members 33c corresponding to the lower winning opening 33b. As a result, the upper winning opening 33a is in an open state in which a game ball can always enter, whereas the lower winning opening 33b is opened and closed by the opening / closing member 33c according to the establishment of a predetermined condition. There is a switch between a closed state where the ball cannot enter and an open state where the game ball can enter. For example, the lower winning opening 33b is when the opening / closing member 33c is in the open state in the normal mode and a specified time (for example, 0.2 seconds) elapses or when a specified number (for example, 1) of game balls have entered. Closed. This opening / closing process is performed only once in the normal mode. Instead of the above configuration, the lower winning opening 33b may be switched between a closed state in which a game ball is difficult to enter and an open state in which the game ball is easier to enter than the closed state.

  The variable display device unit 35 receives a prize for the normal symbol display device 41 that variably displays with the passage of the second opportunity corresponding port 34 as a trigger, and the first opportunity corresponding unit 33 (upper winning port 33a or lower winning port 33b). A special display device 43 that performs variable display as a trigger and a decorative symbol display device 42 that performs variable display in accordance with the variable display by the special display device 43 are provided.

  The normal symbol display device 41 is configured so that “O” or “X” can be lit and displayed as a normal symbol, and each time the game ball passes through the second opportunity corresponding port 34, for example, the normal symbol is changed from “O” to “ Switching display (fluctuation display) is performed at high speed such as “×” → “◯” →. When the change display is stopped for a few seconds with the “◯” symbol (winning symbol), the first opportunity corresponding unit 33 is activated for a predetermined time. The display contents of the normal symbol display device 41 are directly controlled by a main control device 261 described later.

  In addition, when the game ball newly passes through the second opportunity corresponding port 34 during the fluctuation display of the normal symbol display device 41, the corresponding fluctuation display is performed after the end of the fluctuation display performed at that time. It is configured to be performed. That is, the variable display is on standby (held). The maximum number of the variable display to be held is determined for each model of the pachinko machine, but in this embodiment, it is held up to 4 times, and the hold number is lit and displayed by the hold lamp 44. Yes.

  The special display device 43 is provided on the right side of the normal symbol display device 41, and is composed of three-color light emitting diodes (three-color LEDs) having red, green, and blue emission colors. Then, each time the game ball wins the first opportunity corresponding unit 33, a color change display (variable display) is performed, and the lighting mode (lighting color) when the variable display stops determines whether or not it is a big hit. Is displayed.

  More specifically, when the game ball wins the first opportunity corresponding unit 33, the special display device 43 displays the three-color LED at a high speed such as red → green → blue → red →. When a predetermined time elapses, it is determined and displayed in one of the colors. High-speed color change display means, for example, that red, green, and blue are displayed in order every 4 msec. In the case of winning the big hit lottery, at this time, it is determined and displayed in red or green (for example, stopped for several seconds), and a special gaming state occurs. In particular, red is a display indicating that the game mode after the jackpot is a high probability mode, and green is a display indicating that the game mode after the jackpot is a time reduction mode. The display content of the special display device 43 is also directly controlled by the main control device 261.

  Further, when a new game ball wins the first opportunity corresponding unit 33 during the variable display of the special display device 43, the corresponding variable display is performed after the end of the variable display at that time. It has a configuration. That is, the variable display is on standby (held). The maximum number of the variable display to be held is determined for each model of the pachinko machine, but in this embodiment, it is held up to 4 times, and the hold number is lit and displayed by the hold lamp 46. Yes. In addition, when a new game ball wins the first opportunity corresponding unit 33 during the big hit state, the corresponding change display is also suspended.

  The decorative symbol display device 42 is configured as a liquid crystal display device, and display contents are controlled by a sub-control device 262 and a display control device 45 described later. That is, in the decorative symbol display device 42, auxiliary display contents are determined by the sub-control device 262 based on a command from the main control device 261 so as to correspond to the result displayed on the special display device 43, Display is performed by the display control device 45. On the decorative symbol display device 42, for example, three symbol rows of upper, middle and lower are displayed. Each symbol sequence is composed of a plurality of symbols, and these symbols are scrolled and displayed on the decorative symbol display device 42 so as to be scrolled for each symbol sequence, and then the upper symbol sequence → the lower symbol sequence → the middle symbol sequence. Stops are displayed in order. The variable display device unit 35 is provided with a center frame 47 so as to surround the decorative symbol display device 42.

  The variable winning device 32 is normally in a closed state in which a game ball cannot be won, and is in an open state in which a game ball can be won in the case of a big hit (occurrence of a special game state). Specifically, the passage of a specified time (for example, 29 seconds) or a specified number (for example, 10) of winnings is regarded as one round (special prize state), and the large winning opening of the variable winning device 32 is repeated a predetermined number of times (a predetermined number of rounds). Opened.

  The game board 30 includes an inner rail constituting part 51 and an outer rail constituting part 52, and a rail 50 for guiding a game ball launched from the launching device 70 to the upper part of the game board 30 is attached. As a result, the game balls fired in accordance with the turning operation of the handle 18 are guided through the launch rail 61 and the rail 50 into a game area formed between the game board 30 and the glass unit 137.

  A return ball preventing member 53 is attached to the tip portion of the inner rail constituting portion 51 (the upper left portion in FIG. 4). This prevents a situation in which the game ball once guided from the rail 50 to the game area returns to the rail 50 again.

  In the present embodiment, the outer rail component 52 is interrupted at the upper right portion of the game board 30, and the inner rail component 51 is interrupted at the lower right portion of the game board 30. For this reason, the game area is defined by the inner peripheral surface of the rail 50 and the window hole 39 of the resin base 38. However, the parallel part of the inner and outer rail components 51 and 52 is excluded.

  As shown in FIG. 3, on the back side of the front frame set 14, a ball passage 71 is provided below the window portion 101 so as to connect to a discharge port 16 of the lower plate 15 from a payout mechanism portion 352 described later. In addition, there is a gap of a predetermined interval between the firing rail 61 provided on the inner frame 12 and the rail 50 (outer rail constituting portion 52), and the game dropped from the gap on the back side of the front frame set 14 A foul ball passage 72 for guiding the ball to the lower plate 15 is formed. Thus, if the game ball launched from the launching device 70 does not reach the return ball prevention member 53 and returns to the rail 50 as a foul ball, the foul ball is transferred to the lower plate 15 via the foul ball passage 72. Discharged.

  3 and 4 is a payout passage for guiding a game ball paid out by a payout mechanism portion 352, which will be described later, to the front of the inner frame 12, a passage leading to the upper plate 19, and a ball passage. 71 and the passage leading to the lower plate 15. A shutter 68 is provided below the payout passage 67. When the front frame set 14 is opened, the shutter 68 protrudes forward by an urging force of a spring or the like so that the outlet of the payout passage 67 is almost closed. ing. When the front frame set 14 is closed, the shutter 68 is pushed open by the rear end portion on the entrance side of the ball passage 71.

  Next, the back configuration of the pachinko machine 10 will be described with reference to FIGS. Various control boards are arranged on the back of the pachinko machine 10 so as to be lined up, down, left and right, and partially overlapped in the front and back, and further, a game ball supply device (payout mechanism) for supplying game balls And a protective cover made of resin. The dispensing mechanism and the protective cover are integrated as one unit, and the resin portion is generally sometimes referred to as a back pack. Therefore, this unit is referred to as a “back pack unit 203”.

  First, the back configuration of the game board 30 will be described. As shown in FIG. 6, on the back side of the variable display device unit 35 (see FIG. 4) arranged corresponding to the through hole in the center of the game board 30, a resin frame cover that covers the center frame 47 from the back side. 213 is provided to protrude rearward. Further, on the back side of the frame cover 213, a decorative symbol display device 42, a display control device 45, and a sub control device 262, which are liquid crystal display devices facing forward from the opening of the frame cover 213, can be attached and detached in a state where they are stacked in front and back. Is attached.

  The decorative symbol display device 42 is housed in a housing box 42 a in which an opening for exposing the display unit (liquid crystal screen) of the decorative symbol display device 42 to the front side of the pachinko machine 10 is formed, and the rear surface of the frame cover 213. It is fixed on the side. The display control device 45 is accommodated in the substrate box 45a and fixed to the back side of the decorative symbol display device 42 (accommodation box 42a). The sub-control device 262 is accommodated in the substrate box 262a and fixed to the back side of the display control device 45 (substrate box 45a). In the frame cover 213, an LED control board for driving LEDs and the like built in the center frame 47 is disposed. The storage box 42a and the substrate boxes 45a and 262a are made of a transparent resin material or the like so that the inside can be visually recognized.

  Under the frame cover 213, a back frame set 215 is attached to the game board 30 so as to cover the general winning opening 31, the variable winning device 32, the first opportunity corresponding unit 33, and the like from behind. The back frame set 215 includes a ball collection mechanism (not shown) for collecting game balls that have won prizes in various winning ports. The game balls collected by the ball collection mechanism are guided to a discharge passage portion 217 described later, and discharged from the discharge chute of the discharge passage portion 217 to the outside of the pachinko machine 10.

  In the present embodiment, the back frame set 215 functions as a mounting base for the main controller 261. More specifically, the board mounting unit 701 on which the main controller 261 is mounted is pivotally supported with respect to the back frame set 215 and can be opened rearward.

  The main controller 261 is accommodated in a substrate box 263 made of a transparent resin material. As shown in the front view (FIG. 7) and the cross-sectional view (FIG. 8), the substrate box 263 includes a box base 263 a that covers the back side and the periphery of the main controller (main substrate) 261, and an opening of the box base 263 a. As a whole, the box cover 263b that covers is formed into a substantially rectangular parallelepiped shape that is long to the left and right. FIG. 8 is a partial cross-sectional view taken along the line KK of FIG. 7, but the appearance of a caulking pin 267 to be described later is shown for convenience (the same applies to other cross-sectional views hereinafter). The main board (main control device) 261 corresponds to the control board in this embodiment. Accordingly, the substrate box 263 corresponds to the substrate box in the present embodiment.

  The box base 263a and the box cover 263b are connected by a sealing unit 264 as sealing means after the main controller 261 is accommodated. By doing so, the substrate box 263 can be sealed.

  Hereinafter, the sealing unit 264 will be described in detail with reference to the drawings. In the present embodiment, a total of eight sealing units 264 are provided, four on each of the left and right sides of the substrate box 263.

  Each sealing unit 264 of the present embodiment includes a caulking pin 267 that serves as a connecting and holding means for a first connecting portion 265 formed on one of the box base 263a or the box cover 263b and a second connecting portion 266 formed on the other. And it will be in a sealing state by connecting using locking piece 268. The caulking pin 267 constitutes a connecting member in the present embodiment, and the locking piece 268 constitutes a first holding member.

  The 1st connection part 265 makes bottomed substantially cylindrical shape provided with the insertion hole 271 in which the crimp pin 267 is inserted. An insertion hole 272 that communicates with the insertion hole 271 is formed through the second connection part 266 that is assembled to the opening side of the first connection part 265. And the crimp pin 267 will be inserted in the insertion hole 271 of the 1st connection part 265 via the insertion hole 272 from the 2nd connection part 266 side.

  However, in the four sealing units 264 (hereinafter referred to as “type A” for convenience) provided on the left side when viewed from the front of the substrate box 263 and the four sealing units 264 (hereinafter referred to as “type B” for convenience) provided on the right side, The direction in which the caulking pin 267 is inserted is different.

  More specifically, in each type A sealing unit 264, the first connecting portion 265 is integrally formed with the box base 263a via the first separating portion 273, and the second connecting portion 266 is interposed via the second separating portion 274. The box cover 263b is integrally formed. On the other hand, in each type B sealing unit 264, the first connecting portion 265 is formed integrally with the box cover 263b via the first separating portion 273, and the second connecting portion 266 is interposed via the second separating portion 274. The box base 263a is integrally formed. Accordingly, in each type A sealing unit 264, the caulking pin 267 is inserted from the front side of the substrate box 263 (box cover 263b side), whereas in each type B sealing unit 264, the back side of the substrate box 263 (box base) The caulking pin 267 is inserted from the 263a side).

  The first separating portion 273 and the second separating portion 274 are formed thinner than the first connecting portion 265 and the second connecting portion 266, respectively, and the connecting portions 265 and 266 come into contact with each other and are in a connected state. Even in some cases, a gap is formed between the two separating portions 273 and 274. By forming this gap, since the cutting edge of a tool such as a nipper can enter the gap when opening the substrate box 263 as will be described later, each of the separation portions 273 and 274 can be easily and individually provided. Can be cut into pieces.

  The connecting portions 265 and 266 and the separating portions 273 and 274 are formed of a resin material, whereas the caulking pins 267 inserted into the sealing unit 264 are formed of a metal material such as a stainless steel material. As shown in FIG. 9, the caulking pin 267 has a cylindrical shaft portion 267a extending along the predetermined axis C1 direction, and a proximal end side (upper side in FIG. 9) of the shaft portion 267a than the shaft portion 267a. And a large-diameter head 267b.

  Further, a fitting groove 267c is formed along the circumferential direction of the shaft portion 267a on the distal end side (lower side in FIG. 9) of the shaft portion 267a in the vicinity of the distal end portion, that is, a position slightly closer to the proximal end side than the distal end portion. Yes. By forming the fitting groove 267c, the tip of the shaft portion 267a becomes a locking portion 267d. A tapered chamfered portion 267e is formed around the distal end side of the locking portion 267d to facilitate insertion into the insertion hole 271 and the like. A portion where the fitting groove 267c is formed constitutes a constricted portion of the caulking pin 267 corresponding to the locking piece 268 (first holding member).

  The locking piece 268 that engages with the caulking pin 267 is formed of a metal material such as a stainless steel material, like the caulking pin 267.

  As shown in FIG. 10, the locking piece 268 in the present embodiment has an oval shape and has a circular hole 268 a into which the distal end portion (locking portion 267 d) of the caulking pin 267 is inserted. The inner diameter of the hole portion 268a is set to be smaller than the outer diameter of the general portion of the shaft portion 267a of the caulking pin 267, and approximately equal to the diameter of the shaft portion 267a where the fitting groove 267c is formed. A plurality of tongue-like pieces 268c are formed on the peripheral edge of the hole 268a by forming a plurality of cuts 268b extending radially from the center of the hole 268a. As a result, the peripheral edge of the hole 268a is easily elastically deformed, and the tip of the caulking pin 267 can be easily inserted.

  The insertion hole 271 of the first connecting portion 265 into which the caulking pin 267 is inserted has a circular cross section, and the inner diameter thereof is set to be substantially the same as the outer diameter of the shaft portion 267a of the caulking pin 267. . Therefore, when the caulking pin 267 is inserted, there is almost no gap between them. However, a slight clearance is provided in consideration of insertion of the caulking pin 267 and the like.

  In addition, the peripheral wall portion of the first connecting portion 265 has a horizontal hole-shaped slit hole 277 that communicates with the insertion hole 271 at a position opposite to the connection position of the first separation portion 273 and the insertion hole 271. It is formed [see FIG. 11 (a) etc.]. The slit hole 277 constitutes a first lateral hole portion corresponding to the locking piece 268 (first holding member) in the present embodiment.

  The slit hole 277 extends perpendicular to the direction of the axis C <b> 2 of the insertion hole 271, passes through the peripheral wall portion of the first connection portion 265, and opens on the outer peripheral surface of the first connection portion 265. Then, the locking piece 268 is inserted into the first connecting portion 265 from the opening of the slit hole 277.

  A groove portion 278 is formed on the inner peripheral wall surface of the insertion hole 271 so as to be engaged with the slit hole 277 so that the peripheral edge portion of the locking piece 268 inserted from the slit hole 277 is locked.

  The slit hole 277 and the groove 278 are formed corresponding to the oval peripheral shape of the locking piece 268, and the locking piece 268 is inserted in the state where the locking piece 268 is inserted into the first connecting portion 265. The whole is housed in the first connecting portion 265.

  The thickness of the slit hole 277 (the width in the direction of the axis C2) is also set to be substantially the same as the thickness of the locking piece 268. When the locking piece 268 is inserted into the slit hole 277, there is almost no gap therebetween. There is no gap and the contact state is established, and the locking piece 268 is fitted.

  With these configurations, the exposed surface of the inserted locking piece 268 is flush with the outer peripheral surface of the first connecting portion 265 or slightly intruded from the outer peripheral surface. If it will be in this state, the position of the hole 268a of the latching piece 268 will overlap with the insertion hole 271 of the 1st connection part 265 along the axis line C2.

  Of the insertion hole 271 of the first connecting portion 265, the portion on the bottom side of the slit hole 277 and the groove portion 278 is a large-diameter hole portion 271a having a larger diameter than the opening side. This is a device for facilitating deformation of the peripheral portion (tongue-like piece 268c) of the hole 268a of the locking piece 268, as will be described later.

  Further, the second connecting portion 266 has a stepped engagement so that the periphery of the insertion hole 272 is notched on the non-contact surface side with the first connecting portion 265, that is, on the side where the caulking pin 267 is inserted. A recess 279 is formed [see FIG. When the caulking pin 267 is inserted, the head 267b of the caulking pin 267 is locked to the bottom of the engagement recess 279, so that the movement of the caulking pin 267 toward the first connecting portion 265 is restricted. In this state, the head 267b of the caulking pin 267 is immersed more than the end surface of the second connecting portion 266 on the non-contact side (see FIG. 11D and the like).

  Next, a procedure for sealing the substrate box 263 by the sealing unit 264 will be described. First, the box cover 263b is assembled to the box base 263a in a state where the main controller 261 is accommodated. More specifically, a plurality of locking portions 285 are formed on the upper side and lower side of the box base 263a so as to protrude in a substantially L shape so that the front end faces rightward when viewed from the front of the substrate box 263. A slit 286 is formed on the upper side and the lower side of the box cover 263b corresponding to each locking portion 285. Then, when assembling, first, the box cover 263b is put on the box base 263a so that the locking portions 285 are inserted into the corresponding slits 286, respectively. Subsequently, the box cover 263b is slid leftward. Thereby, each latching | locking part 285 is latched by the box cover 263b, it will be in the state by which the movement of the box cover 263b to the board | substrate box 263 front side was controlled, and assembly | attachment is completed (refer FIG. 7).

  When the assembly of the board box 263 is completed, as shown in FIG. 11A, the first connecting portion 265 and the second connecting portion 266 constituting each sealing unit 264 come into contact with each other, and the insertion hole 271 and the insertion hole 272 are brought into contact. Will be in communication.

  In this state, the locking piece 268 is inserted into the slit hole 277 of one of the four sealing units 264 of type A (left side) as shown in FIG. Similarly, the locking piece 268 is inserted into the slit hole 277 for one of the four sealing units 264 of type B (right side). FIG. 7 shows a state in which the uppermost one is used in type A and the lowermost one is used in type B. However, the present invention is not limited to this, and at least one each of types A and B is shown. Any combination is possible as long as they are combined and used as one set.

  Subsequently, as shown in FIG. 11B, the caulking pins 267 are respectively inserted into the pair of type A and B sealing units 264 into which the locking pieces 268 are inserted. Again, at this time, in the type A sealing unit 264, the caulking pin 267 is inserted from the box cover 263b side, and in the type B sealing unit 264, the caulking pin 267 is inserted from the box base 263a side.

  When the shaft portion 267a of the caulking pin 267 is inserted into the insertion hole 271 of the first connecting portion 265, the tip of the shaft portion 267a (the locking portion 267d) is the peripheral portion of the hole portion 268a of the locking piece 268. It hits (tongue piece 268c). Further, when the head 267b of the caulking pin 267 is pushed down and the caulking pin 267 is pushed in, the locking portion 267d of the caulking pin 267 elastically moves the peripheral portion (tongue-like piece 268c) of the hole 268a of the locking piece 268. While being deformed (see FIG. 11C), it penetrates into the insertion hole 271 and is accommodated in the large-diameter hole 271a (see FIG. 11D). Since the large-diameter hole portion 271a is formed, on the bottom side of the insertion hole 271, there are few portions that support the tongue-like piece 268c of the locking piece 268. Therefore, the tongue-like piece 268c is inserted into the insertion hole 271. It becomes easy to bend to the bottom side. In other words, the tongue-like piece 268c is unlikely to bend toward the opening side of the insertion hole 271 due to the step between the general portion of the insertion hole 271 and the large-diameter hole portion 271a. Therefore, as will be described later, in the state where the tongue-like piece 268c is engaged with the locking portion 267d of the caulking pin 267 as the locking claw (locking portion), the caulking pin 267 is more reliably prevented from coming off. It will be.

  As shown in FIG. 11D, when the locking portion 267d of the caulking pin 267 penetrates the hole 268a of the locking piece 268, the tongue-like piece 268c at the periphery of the hole 268a is restored, so that the caulking pin 267 is fitted into the fitting groove 267c. As a result, both the caulking pin 267 and the locking piece 268 are in a state where they cannot be removed. However, the tongue-like piece 268c at the periphery of the hole 268a is not completely restored, is slightly curved toward the bottom side of the insertion hole 271, and is a locking claw (engagement) that locks the locking portion 267d of the caulking pin 267. To play a role. Similarly, the head 267b of the caulking pin 267 is locked to the bottom of the engaging recess 279 of the second connecting portion 266, so that the movement of the caulking pin 267 toward the first connecting portion 265 is restricted. Is done.

  Finally, as shown in FIG. 11D and the like, the blocking portion 300 is formed by pouring a resin material such as an ultraviolet curable resin into the engaging recess 279 of the second connecting portion 266 and curing it. To do. As a result, the caulking pin 267 cannot be removed from the second connecting portion 266.

  Thus, when the 1st connection part 265 and the 2nd connection part 266 will be in a connection state, the board | substrate box 263 will become unopenable and sealing will be completed.

  Next, a procedure for opening the substrate box 263 in the sealed state when the main controller 261 is taken out from the substrate box 263 for inspection or when the failed main controller 261 is replaced will be described.

  In order to open the substrate box 263, it is necessary to cut the sealing unit 264 being used from the substrate box 263 with a tool such as a nipper.

  Of course, in the sealing unit 264 being used, the substrate box 263 can be opened by cutting both the first separation part 273 and the second separation part 274 and completely removing the used sealing unit 264. However, in this case, the used sealing unit 264 does not remain, and the trace of opening the substrate box 263 becomes inconspicuous.

  In addition, in this embodiment, when opening the substrate box 263, the box cover 263b must be slid once to the right and removed, contrary to the assembly procedure. Therefore, depending on how to cut, the used sealing unit 264 may interfere with the sliding of the box cover 263b.

  For the above reasons, in this embodiment, the substrate box 263 is opened by the following method. First, as shown in FIG. 12, in the type A sealing unit 264, the second separating portion 274 connected to the box cover 263b is cut (see the cutting line H1), and in the type B sealing unit 264, The second separation part 274 connected to the box base 263a is cut (see the cutting line H2). By doing so, the sealing of the substrate box 263 is released, and the box cover 263b can be slid rightward from the box base 263a and removed as shown in FIG.

  Temporarily, contrary to the above configuration (first cutting pattern cut along cutting lines H1 and H2), in type A sealing unit 264, first separating portion 273 connected to box base 263a is cut and type In the B sealing unit 264, when the first separation portion 273 formed to be connected to the box cover 263b is cut (second cutting pattern), the used sealing unit 264 prevents the box cover 263b from sliding, The box cover 263b cannot be removed from the box base 263a.

  Similarly, when the first separation part 273 is cut in the type A sealing unit 264 and the second separation part 274 is cut in the type B sealing unit 264 (third cutting pattern), or the type A sealing unit When the second separation part 274 is cut at H.264 and the first separation part 273 is cut at the type B sealing unit 264 (fourth cutting pattern), the used sealing unit 264 is not used for sliding the box cover 263b. As a result, the box cover 263b cannot be removed from the box base 263a.

  However, this is because the present embodiment has a configuration in which the box cover 263b is slid and attached to and detached from the box base 263a, and both are mounted on the board surface of the main controller (main board) 261. Can be opened by any of the first to fourth cutting patterns as long as it is mounted and removed by moving in a direction perpendicular to the vertical direction (vertical direction in FIG. 12).

  With the above configuration, when the substrate box 263 is opened (including the case where both the first separating portion 273 and the second separating portion 274 are cut and the sealing unit 264 is completely removed) You can leave a history. If the opening history of the board box 263 is left in the board box 263, it is possible to easily find out whether or not unauthorized opening has been performed by looking at the board box 263. Therefore, unauthorized opening after sealing can be prevented, and even if unauthorized opening is performed, such a situation can be detected early and easily. As described above, when both the first separating portion 273 and the second separating portion 274 are cut and the used sealing unit 264 is completely removed, the used sealing unit 264 remains. However, the trace of opening the substrate box 263 becomes inconspicuous, but the trace does not remain. That is, when the sealing unit 264 is completely excised, a trace that the separation parts 273 and 274 are cut by a tool or a history that the sealing unit 264 has disappeared remains, so that it is possible to easily detect an illegal act.

  In this embodiment, since four sets of four each of type A and B sealing units 264 are provided, the unused portions even after the separation portions 273 and 274 are cut and the substrate box 263 is once opened. By newly inserting the caulking pin 267 and the locking piece 268 into the sealing unit 264 (the first connecting portion 265 and the second connecting portion 266) and forming the closing portion 300, the sealing process is performed up to the remaining three times. Is possible.

  Now, the game board 30 corresponds to various winning ports such as a general winning port 31 as a winning means and detects a game ball that has entered the various winning holes (entrance detecting means). Is provided. Specifically, as shown in FIG. 4, a winning opening switch 221 is provided at a position corresponding to the general winning opening 31, and a count switch 223 is provided in the variable winning device 32. The first opportunity corresponding unit 33 is provided with first opportunity corresponding unit switches 224a and 224b corresponding to the upper winning opening 33a and the lower winning opening 33b, respectively. Further, a second opportunity corresponding port switch 225 is provided at a position corresponding to the second opportunity corresponding port 34.

  Although not shown, the back frame set 215 is provided with a first board surface relay board that is electrically connected to the prize opening switch 221, the count switch 223, and the second opportunity corresponding port switch 225 via a cable connector. It has been. The first board surface relay board relays the prize opening switch 221 and the like and the main control device 261 as control means, and is electrically connected to the main control device 261 through a cable connector.

  On the other hand, the first opportunity corresponding switches 224a and 224b that detect the entry into the first opportunity corresponding unit 33 (the upper winning opening 33a or the lower winning opening 33b) are directly connected via the connector cable without passing through the relay board.

In a state where the caulking pin 267 is inserted and the head 267b is immersed in the engaging recess 279, there is almost no gap between the outer peripheral portion of the head 267b of the caulking pin 267 and the inner peripheral wall portion of the engaging recess 279. It is not formed. However, a slight clearance is provided in consideration of insertion of the caulking pin 267 and the like.

  Furthermore, a second fitting groove 267f is formed along the circumferential direction of the shaft portion 267a at the boundary portion between the head portion 267b of the caulking pin 267 and the shaft portion 267a. By forming the second fitting groove 267f, the portion becomes a narrow neck portion 267g. And the 2nd latching piece 290 shown in FIG. 18 is fitted by the said neck part 267g. The second locking piece 290 corresponds to the second holding member in the present embodiment. Therefore, the neck portion 267g of the caulking pin 267 constitutes a constricted portion corresponding to the second holding member.

  Like the locking piece 268, the second locking piece 290 is formed in a small size by a metal material. The second locking piece 290 is formed with a fitting recess 290a that fits into the neck 267g of the caulking pin 267 so that a part of the peripheral edge is cut away. The fitting recess 290a has an opening narrower than the back side so as to prevent the caulking pin 267 from falling off the neck 267g. This shape substantially matches the cross-sectional shape of the neck portion 267g of the caulking pin 267. As a result, the fitting recess 290a is fitted to the neck 267g of the caulking pin 267 with almost no gap.

  In addition, a lateral slit-shaped slit hole 293 that communicates with the insertion hole 272 is formed in the peripheral wall portion of the second connection portion 266 at a position that is opposite to the connection position of the second separation portion 274 and the insertion hole 272. [Refer to FIG. 19 (a) etc.]. The slit hole 293 constitutes a second lateral hole portion corresponding to the second locking piece 290 (second holding member).

  The slit hole 293 extends perpendicular to the direction of the axis C <b> 2 of the insertion hole 272, passes through the peripheral wall portion of the second connection portion 266, and opens on the outer peripheral surface of the second connection portion 266. Then, the second locking piece 290 is inserted into the second connecting portion 266 from the opening of the slit hole 293.

  The slit hole 293 is formed corresponding to the oval peripheral shape of the second locking piece 290, and in the state where the second locking piece 290 is inserted into the second connecting portion 266, the second hole The entire locking piece 290 is accommodated in the second connecting portion 266.

  The thickness of the slit hole 293 (width in the direction of the axis C2) is also set to be substantially the same as the thickness of the second locking piece 290, and in the state where the second locking piece 290 is inserted into the slit hole 293, , There is almost no gap between them, and a contact state is established, and the second locking piece 290 is fitted.

  With these configurations, the exposed surface of the inserted second locking piece 290 is in a state of being flush with the outer peripheral surface of the second connecting portion 266 or slightly more than the outer peripheral surface. If it will be in this state, the position of the fitting recessed part 290a of the 2nd locking piece 290 will overlap with the penetration hole 272 of the 2nd connection part 266, and the axis line C2.

  Next, a procedure for sealing the substrate box 263 by the sealing unit 264 in this embodiment will be described. First, the box cover 263b is assembled to the box base 263a in a state where the main controller 261 is accommodated. In the present embodiment, the box cover 263b is moved and attached in a direction orthogonal to the substrate surface of the main controller (main substrate) 261 to be attached and removed.

  When the assembly of the board box 263 is completed, as shown in FIG. 19A, the first connecting portion 265 and the second connecting portion 266 constituting each sealing unit 264 come into contact with each other, and the insertion hole 271 and the insertion hole 272 are brought into contact with each other. Will be in communication.

  In this state, as in the first embodiment, each of the four sealing units 264 of type A (left side) and type B (right side) has a slit hole as shown in FIG. After inserting the locking piece 268 into 277, the caulking pin 267 is inserted.

  When the shaft portion 267a of the caulking pin 267 is inserted into the insertion hole 271 of the first connecting portion 265, the locking portion 267d of the caulking pin 267 is moved to the peripheral portion (tongue-like shape) of the hole portion 268a of the locking piece 268. The piece 268c) is elastically deformed (see FIG. 19B), penetrates into the insertion hole 271 and is accommodated in the large-diameter hole portion 271a (see FIG. 19C). At the same time, the tongue-like piece 268c at the periphery of the hole 268a is restored and fitted into the fitting groove 267c of the caulking pin 267. As a result, both the caulking pin 267 and the locking piece 268 are in a state where they cannot be removed. In the same manner, the head 267 b of the caulking pin 267 is immersed in the engaging recess 279 of the second connecting portion 266.

  Subsequently, as shown in FIG. 19C, the second locking piece 290 is inserted into the slit hole 293 with the fitting recess 290a at the head. As the second locking piece 290 is inserted, the insertion-side tip of the second locking piece 290 hits the neck 267g of the caulking pin 267. Further, when the second locking piece 290 is pushed in, the neck 267g of the caulking pin 267 is elastically deformed so that the narrow opening of the fitting recess 290a is widened. When this portion passes the neck portion 267g, the tip end portion of the second locking piece 290 is restored, and the second locking piece 290 is fitted to the neck portion 267g of the caulking pin 267 (see FIG. 19D). Thereby, both the caulking pin 267 and the second locking piece 290 are in a state in which they cannot be removed.

  Thus, when the 1st connection part 265 and the 2nd connection part 266 will be in a connection state, the board | substrate box 263 will become unopenable and sealing will be completed.

  In the present embodiment, the substrate box 263 can be opened by any of the first to fourth cutting patterns described in the first embodiment.

  By doing in this way, the effect similar to the said embodiment is show | played. In addition, this embodiment is superior in terms of workability compared to the first embodiment because the operation of embedding the caulking pin 267 with a resin material is not required in the second connecting portion 266.

  In addition, it is not limited to the description content of embodiment mentioned above, For example, you may implement as follows.

  (A) In the above embodiment, the present invention is applied to the sealing configuration for sealing the substrate box 263 containing the main control device 261. However, the present invention is not limited to this, and of course the substrate box 311a of the dispensing control device 311 is used. Of course, the present invention may be applied to other board boxes such as a board box 262a that houses the sub-control device 262.

  (B) The number and configuration of the sealing units 264 are not limited to the above embodiment. For example, in the above-described embodiment, the first connecting portion 265 is configured such that the caulking pin 267 is inserted after the locking piece 268 is inserted and the both engage with each other. As in the relationship with the second locking piece 290, the locking piece 268 may be inserted after the caulking pin 267 is inserted, and both may be engaged. Similarly, in the second connecting portion 266, the caulking pin 267 may be inserted after the second locking piece 290 is inserted, and both may be engaged.

  In addition, a through hole having a horizontal hole is formed in the shaft portion 267a of the caulking pin 267, and a return pin or the like used as a holding member is inserted into the through hole so that the two intersect with each other. Thereby, it is good also as a structure which cannot be extracted from the 1st connection part 265 or the 2nd connection part 266.

  As a specific example, a substantially plate-like connecting member 800 as shown in FIG. 20 may be used instead of the substantially bar-shaped caulking pin 267 of each of the above embodiments. Hereinafter, this embodiment will be described with reference to FIGS. However, the same components as those in the above embodiments are given the same reference numerals, and detailed descriptions thereof are omitted.

  The connecting member 800 used in the sealing unit 264 of the present embodiment is formed of a metal material, like the caulking pin 267 of each of the above embodiments. As shown in FIG. 20, the connecting member 800 has a rectangular shape, and slit holes 800 c into which holding pins 850 as holding members are inserted are formed at two locations in the longitudinal direction.

  The holding pin 850 is made of a metal material, and has a substantially flat plate portion 850a inserted into the first connecting portion 265 or the second connecting portion 266, and is integrally formed with the first connecting portion 265 or And a head portion 850b engaged with the second connecting portion 266, and has a substantially T shape in front view. More specifically, the flat plate portion 850a has a rectangular shape, and the head portion 850b is formed in a cylindrical shape so that one end side in the longitudinal direction of the flat plate portion 850a is wound. Then, in the vicinity of the tip of the flat plate portion 850a on the side opposite to the head portion 850b, a part of the flat plate portion 850a is cut out in a U-shape, thereby forming two locking claws 850c having the head portion 850b side as a free end. Has been. These locking claws 850c protrude from the front and back surfaces of the flat plate portion 850a by bending the free end sides in opposite directions. Of the holding pins 850, the one inserted into the first connecting portion 265 corresponds to the first holding member in the present embodiment, and the one inserted into the second connecting portion 266 corresponds to the second holding member.

  In the present embodiment, the internal structures of the first connecting portion 265 and the second connecting portion 266 that constitute the sealing unit 264 are also different from the above-described embodiments in accordance with the configurations of the connecting member 800 and the holding pin 850. Different changes have been made.

  For example, the insertion hole 271 of the first connection part 265 and the insertion hole 272 of the second connection part 266 are both formed in a relatively narrow cross-sectional rectangular shape (slit shape) in accordance with the connection member 800. Yes. In addition, the engagement concave portion 279 of the second connecting portion 266 is also omitted in accordance with the omission of the head and the like. As a result, when the connecting member 800 is inserted into the sealing unit 264 and is immersed, almost no gap is formed between the connecting member 800 and the insertion hole 271 and the insertion hole 272.

  Further, on the opening side of the slit holes 277 and 293 of the first connecting part 265 and the second connecting part 266 into which the holding pin 850 is inserted, there are stepped engaging concave parts 277a and 293a so that the periphery thereof is cut out. Is formed. When the holding pin 850 is inserted, the head 850b of the holding pin 850 is engaged with the engaging recesses 277a and 293a in an immersive state.

  On the inner peripheral wall surface of the insertion hole 271 that faces the slit hole 277 and the inner peripheral wall surface of the insertion hole 272 that faces the slit hole 293, the housing recesses 277b and 293b that respectively accommodate the tip portions of the holding pins 850 are accommodated. Is formed.

  As a sealing procedure, first, as shown in FIG. 21A, the connecting member 800 is inserted into the insertion hole 271 of the first connection portion 265 and the insertion hole 272 of the second connection portion 266 that are in the communication state. Then, as shown in FIG. 21B, the connecting member 800 is accommodated in a state of being immersed in the sealing unit 264. In this state, the slit holes 800c of the connecting member 800 are overlapped with the extension lines of the slit holes 277 of the first connecting portion 265 and the slit holes 293 of the second connecting portion 266, respectively.

  Subsequently, as shown in FIG. 21B, the holding pin 850 is inserted into the slit hole 277 of the first connecting portion 265. When the holding pin 850 is pushed in, both the locking claws 850c are elastically deformed, and the holding pin 850 is inserted into the slit hole 277. When both the locking claws 850 c of the holding pin 850 pass through the slit hole 800 c of the connecting member 800, both the locking claws 850 c are elastically restored and received in the receiving recess 277 b and are locked by the connecting member 800. [See FIG. 21 (c)]. At the same time, the head 850b of the holding pin 850 is engaged with the engaging recess 277a of the first connecting portion 265 in an immersive state. As a result, both the connecting member 800 and the holding pin 850 cannot be removed at the first connecting portion 265. However, in this embodiment, the connecting member 800 and the holding pin 850 are not detachably engaged with each other, and both of them can be extracted, but are accommodated in the first connecting portion 265, and both When the engagement state is not released, the state becomes impossible to extract.

  Similarly, as shown in FIG. 21C, the holding pin 850 is inserted into the slit hole 293 of the second connecting portion 266. When the holding pin 850 is pushed in, both the locking claws 850c are elastically deformed, and the holding pin 850 is inserted into the slit hole 293. When both the locking claws 850c of the holding pin 850 pass through the slit hole 800c of the connecting member 800, the both locking claws 850c are elastically restored and received in the receiving recess 293b, and are locked by the connecting member 800. [See FIG. 21 (d)]. At the same time, the head portion 850b of the holding pin 850 is engaged in an engaged state with the engagement recess 293a of the second connecting portion 266. As a result, both the connecting member 800 and the holding pin 850 are in a state in which they cannot be removed at the second connecting portion 266. However, similarly to the above, the connecting member 800 and the holding pin 850 are not engaged with each other so as not to be extracted, and both can be extracted but are accommodated in the second connecting portion 266 and both When the engagement state is not released, the state becomes impossible to extract.

  Thus, when the 1st connection part 265 and the 2nd connection part 266 will be in a connection state, the board | substrate box 263 will become unopenable and sealing will be completed.

  (C) In each of the above embodiments, a configuration in which the connecting member such as the caulking pin 267 is locked by the holding member such as the locking piece 268 is described, but the holding member such as the locking piece 268 is omitted. It is good.

  As a specific example, there is an example in which a caulking pin 870 having a substantially plate-like body as shown in FIG. 22 is used instead of the caulking pin 267 having a substantially rod-like body in each of the above embodiments. Hereinafter, this embodiment will be described with reference to FIGS. However, the same components as those in the above embodiments are given the same reference numerals, and detailed descriptions thereof are omitted.

  The caulking pin 870 as a connecting member used in the sealing unit 264 of the present embodiment is almost the same except that it includes two sets of locking claws locked to the first connecting portion 265 and the second connecting portion 266. The configuration is the same as that of the holding pin 850 in the embodiment described in (b) above. That is, as shown in FIG. 22, the caulking pin 870 includes a substantially flat plate portion 870 a inserted into the first connection portion 265 and the second connection portion 266, a head portion 800 b formed integrally therewith, A set of locking claws 870c provided near the tip of the flat plate portion 870a on the opposite side of the head 800b, and a set of locking claws 870d provided closer to the head 870b. ing.

  Also in the present embodiment, the internal structure and the like of the first connecting portion 265 and the second connecting portion 266 are changed in accordance with the configuration of the caulking pin 870. For example, the slit holes 277 and 293 are omitted in the first connecting portion 265 and the second connecting portion 266, and both engagements on the bottom side of the insertion hole 271 of the first connecting portion 265 are fixed on the tip side of the caulking pin 870. A storage chamber 861 in which the claw 870c is stored is formed, and a storage chamber 863 in which both the locking claw 870d on the head 870b side is stored is formed in the middle of the insertion hole 272 of the second connecting portion 266. . Further, the shape of the engaging recess 279 of the second connecting portion 266 is also set according to the shape of the head 870b of the caulking pin 870, and the caulking pin 870 is inserted into the sealing unit 264, and the head 870b is engaged. In the state of being immersed in the joint recess 279, almost no gap is formed between the head 870b and the side wall of the engagement recess 279.

  As a sealing procedure, first, as shown in FIG. 23A, the caulking pin 870 is inserted into the insertion hole 271 of the first connection part 265 and the insertion hole 272 of the second connection part 266 that are in a communication state. . When the caulking pin 870 is pushed in, first, both locking claws 870c on the distal end side are inserted into the insertion hole 272 while being elastically deformed. Subsequently, when both the locking claws 870c on the distal end side are inserted into the insertion hole 271, both the locking claws 870d on the head 870b side are inserted into the insertion hole 272 while being elastically deformed. Then, as shown in FIG. 23B, when both the locking claws 870c on the distal end reach the storage chamber 861, the both locking claws 870c are elastically restored and locked to the wall surface of the storage chamber 861. It will be in the state. At the same time, both locking claws 870 d on the head 870 b side reach the storage chamber 863, so that both locking claws 870 d are also elastically restored and locked to the wall surface of the storage chamber 863. In this state, the head portion 870 b of the caulking pin 870 is also engaged in the state where it is immersed in the engaging recess 279 of the second connecting portion 266. As a result, the operation of releasing the locked state of the two sets of locking claws 870c and 870d cannot be performed, and the caulking pin 870 cannot be removed from the first connecting portion 265 and the second connecting portion 266, respectively.

  Thus, when the 1st connection part 265 and the 2nd connection part 266 will be in a connection state, the board | substrate box 263 will become unopenable and sealing will be completed.

  Further, in addition to such a configuration, for example, as shown in FIG. 24, the slit holes 277 and 293 are not omitted in the first connecting portion 265 and the second connecting portion 266 so as to communicate with the storage chambers 861 and 863. 2, after completion of the locking of the caulking pin 870, a resin material 864 such as an ultraviolet curable resin is poured into the storage chambers 861 and 863 through the slit holes 277 and 293, and is cured. If the locking state of the pawls 870c and 870d is made unreleasable, the caulking pin 870 cannot be more reliably extracted from the first connecting portion 265 and the second connecting portion 266. However, the configuration using the holding member such as the locking piece 268 as in the above embodiment is preferable in terms of workability because the operation of pouring the resin material 864 and the like is not required.

  (D) In the above embodiment, in each type A sealing unit 264, the first connecting portion 265 is formed on the box base 263a, and the second connecting portion 266 is formed on the box cover 263b. On the other hand, in each type B sealing unit 264, the first connecting portion 265 is formed on the box cover 263b, and the second connecting portion 266 is formed on the box base 263a. That is, the direction in which the caulking pin 267 is inserted is different. Not only this but the sealing unit 264 of both type A and B used by 1 set is good also as a structure where the direction which inserts the crimp pin 267 is the same. That is, both the type A and B sealing units 264 may have a configuration in which the first connecting portion 265 is formed on the box base 263a and the second connecting portion 266 is formed on the box cover 263b. Alternatively, both the type A and B sealing units 264 may be configured such that the first connecting portion 265 is formed on the box cover 263b and the second connecting portion 266 is formed on the box base 263a.

  In addition, it is not necessary to use two sealing units 264 as a set, and even when only one sealing unit 264 is used, there are sufficient effects to solve the above problems. Even if the sealing units 264 of both types A and B are not necessarily used in one set, if one sealing unit 264 of the present invention is used, one of the box base 263a and the box cover 263b can be left without leaving any trace of opening. Since it cannot be obtained without being damaged, an illegal act such as replacement of the entire board box 263 described above can be suppressed. Of course, it is more preferable to use a pair of sealing units 264 of both types A and B, since both the box base 263a and the box cover 263b can leave traces of opening.

  (E) In the above embodiment, four sealing units 264 are provided on each of the left and right sides of the substrate box 263. The arrangement of the sealing unit 264 is not limited to this. For example, the type A and B sealing units 264 may be provided on the upper side of the substrate box 263 one by one.

  (F) In the above embodiment, a metal member is used as the connecting member such as the caulking pin 267 and the holding member such as the locking piece 268, but the material of the connecting member and the holding member is limited to this. For example, other relatively hard materials such as ceramic and hard resin may be used.

  (G) In the first embodiment, as shown in FIG. 25, a plurality of locking portions formed in a substantially L-shape projecting from the upper side and the lower side of the box base 263a so that the tip faces rightward. 285 is formed, and slits 286 are formed on the upper side and lower side of the box cover 263b corresponding to the respective locking portions 285. Then, when assembling, first, the box cover 263b is put on the box base 263a so that the locking portions 285 are inserted into the corresponding slits 286, respectively. Subsequently, the box cover 263b is slid leftward. Thereby, each latching | locking part 285 is latched by the box cover 263b, and an assembly | attachment is completed. Here, when the assembly is completed, each locking portion 285 is exposed on the front surface of the box cover 263b. From the viewpoint of preventing fraud, each locking portion 285 is locked in the box cover 263b. It is preferable that each of the locking portions 285 is covered so as not to be exposed to the outside.

  On the other hand, in the second embodiment, the box cover 263b is moved and attached in a direction orthogonal to the substrate surface of the main controller (main substrate) 261 to be attached and removed. However, when the box base 263a and the box cover 263b are attached and removed in this way in parallel with the insertion direction of the connecting member such as the caulking pin 267, the board box 263 is not completely opened. 263 may be forcibly opened, and there is a risk that fraudulent acts may be performed inside the gap. Therefore, from the viewpoint of preventing fraud, the slide type in which the box base 263a and the box cover 263b are assembled so as to intersect the insertion direction of the connecting member such as the caulking pin 267 as in the first embodiment. preferable. More preferably, a larger slide amount is required for attachment and removal. For example, there are specific examples as shown below. In the configuration shown in FIG. 26, guide rails 263g are provided on the upper side and the lower side of the box base 263a, and the flanges 263f on both upper and lower edges of the box cover 263b are fitted inside the guide rail 263g. Thus, the box base 263a and the box cover 263b are attached and removed by sliding along the guide rail 263g. In this case, the main control device (main board) 261 is attached to the box cover 263b side in consideration of protrusions of connector terminals and the like which are omitted in the drawing.

  (H) In the above-described embodiment, the insertion direction of the connecting member such as the caulking pin 267 and the insertion direction of the holding member such as the locking piece 268 are orthogonal to each other. It may not be engaged. For example, it is good also as a structure engaged in the state which the holding member inclined with respect to the connection member.

  (I) You may implement as a pachinko machine of a different type from the said embodiment. In addition to pachinko machines, the game is implemented as an arrangement ball machine, various types of game machines such as sparrow balls, slotted machines such as slot machines, and a game machine that combines slot machines and pachinko machines. Also good.

  The present invention relates to a gaming machine such as a pachinko machine.

  As a kind of gaming machine, a pachinko gaming machine, a slot machine, and the like are known. These gaming machines include a control board (control device) on which electronic components such as a CPU (central processing unit) and a ROM storing a control program related to the game are mounted, and a series of games can be performed by the control board. It is controlled.

In this kind of game machine, has been cheating the many reports of the control board, various fraud measures have been studied. For example, fraud countermeasures are adopted such that the substrate box has a sealing structure (so-called caulking structure), and when the substrate box is opened, an unsealing history (opening trace) due to destruction or the like remains. Reference 1).

In general, a substrate box having a sealing structure is provided in a box base that accommodates a control board, a box cover that closes an opening of the box base, a base-side connecting portion provided in the box base, and a box cover. The box base and the box cover are connected by inserting a caulking member into these .

JP 2003-180917 A

  However, two board boxes having the above-mentioned configuration are prepared, and one of the board boxes is opened by breaking the cover side connecting portion, and the other board box is connected to the base side. When the substrate box is opened by destroying the portion, a box base and a box cover that are intact (no trace of opening) can be obtained.

Houses unauthorized control board in the box base and the box cover obtained as this, when the fraud was performed such exchanges each substrate box, appearance, it is no longer know which control board is replaced , It becomes very difficult to find the fraud.

The above exemplified challenges like is not limited to the pachinko machine, a problem also applicable to other gaming machines with similar substrate box.

  The present invention has been made to solve the above-described problems and the like, and an object of the present invention is to provide a gaming machine including a board box that can leave a trace of opening more reliably.

As described above, pachinko gaming machines, slot machines, and the like are known as a type of gaming machine. These gaming machines include a control board (control device) on which electronic components such as a CPU (central processing unit) and a ROM storing a control program related to the game are mounted, and a series of games can be performed by the control board. It is controlled.

In this type of gaming machine, for the purpose of obtaining illegal profits, the control board is illegally removed and the ROM of the board (if the CPU or ROM is integrated into one chip)
Many illegal actions against the control board have been reported, such as changing the game content by changing the game, or inputting an illegal electrical signal from the outside to the control board via lead wires etc. It is being considered. For example, fraud countermeasures are adopted such that the substrate box has a sealing structure (so-called caulking structure), and when the substrate box is opened, an unsealing history (opening trace) due to destruction or the like remains. Reference 1).

In general, a substrate box having a sealing structure is provided in a box base that accommodates a control board, a box cover that closes an opening of the box base, a base-side connecting portion provided in the box base, and a box cover. And a cover side connecting portion. Then, when the box base and the box cover are assembled, the locking recess formed in the base side connecting portion and the locking hole formed in the cover side connecting portion are aligned and locked via the locking hole. The box base and the box cover are connected to each other by inserting a crimped member such as a pin with a bar, a broken screw, a one-way screw or the like into the recess. The breaking screw is a special screw that can be removed after screwing a portion where a tool engaging portion (cross groove or the like) to which a tool such as a driver is engaged is formed. A one-way screw is a tool engaging part that is engaged in the tightening direction (screwing direction) of a tool such as a screwdriver on the screw head, and the tool such as a screwdriver is rotated in the direction of loosening the screw. If it is, it is a special screw that cannot be removed when the tool is idle.

Therefore, the caulking member inserted into the locking hole and the locking recess cannot be removed unless at least one of the base side connecting portion and the cover side connecting portion is broken (removed). That is, when the substrate box is opened, a predetermined mark is formed on the substrate box, so that if the substrate box is tampered with, it can be detected early and easily.

However, two board boxes having the above-mentioned configuration are prepared, and one of the board boxes is opened by breaking the cover side connecting portion, and the other board box is connected to the base side. When the substrate box is opened by destroying the portion, a box base and a box cover that are intact (no trace of opening) can be obtained.

For example, an intact box cover can be easily obtained by destroying the base side connecting portion and removing the head portion of the caulking member from the cover side connecting portion. On the other hand, regarding the acquisition of the box base, even when a broken screw or a one-way screw is used as a caulking member, the cover side connecting portion is broken, etc. If it is pinched with a tool and turned, it can be removed. When a return pin or the like is used, it can be easily pulled out as long as a part thereof can be clamped by a tool such as a pliers. In this way, an intact box base and box cover with the caulking member removed can be obtained from the two substrate boxes.

When an illegal act such as storing an illegal control board in the box base and the box cover obtained in this way and replacing the entire board box is performed, it is not apparent from the appearance that the control board has been replaced, It becomes very difficult to find the fraud.

In addition, the said subject is a problem applicable not only to a pachinko machine but other game machines which have the same board | substrate box.

The present invention has been made to solve the above-described problems and the like, and an object of the present invention is to provide a gaming machine including a board box that can leave a trace of opening more reliably.

  Hereinafter, each means suitable for solving the above-described problems will be described in terms of items. In addition, the effect etc. peculiar to a corresponding means are added as needed.

Means 1. A gaming machine comprising a control board, a board box containing the control board, and sealing means for sealing the board box,
The sealing means is
When the first connecting part provided in one of the box base and the box cover constituting the board box and the second connecting part provided in the other are connected using a connecting member,
A gaming machine, wherein the connecting member is locked to the first connecting portion and the second connecting portion so as not to be extracted.

  According to the said means 1, a connection member is latched with respect to a 1st connection part and a 2nd connection part so that extraction is impossible. For this reason, in the substrate box having the configuration of the means 1 provided with the first connecting portion on the box base and the second connecting portion on the box cover, the first connecting portion on the box base side is broken to remove the substrate box. When opened, the connecting member cannot be removed from the second connecting portion unless the second connecting portion on the box cover side is destroyed, and an intact box cover cannot be obtained. Similarly, when the second connecting portion on the box cover side is broken and the substrate box is opened, the connecting member can be removed from the first connecting portion unless the first connecting portion on the box base side is broken. You can't get an intact box base. That is, even if two substrate boxes having the configuration of the present means 1 are prepared, both the box base and the box cover cannot be obtained without leaving any trace of opening. In other words, it is possible to more reliably leave a trace of opening the substrate box, and thus to suppress an illegal act such as replacement of the entire substrate box.

  The above-mentioned “control board” in the gaming machine is one of “control boards that control predetermined control relating to games”, for example, “main board (main control board)”, “payout control board”, “display control” Various control boards such as “Board” can be cited as examples. Among these, the “Main Board” that directly controls the player's profit, that is, the “main board” that controls the game value assignment (payout of prize balls, etc.) If the sealing structure is employed as a sealing structure such as a “dispensing control board”, the above-described effects are particularly effective.

  In addition, as described above, the “unable to pull out” means that the connecting member cannot be removed from the connecting portion unless the first connecting portion or the second connecting portion is destroyed. It means that the release operation of the locked state of the connecting member in the portion cannot be performed.

Mean 2. The connecting member is inserted into the first connecting part through the second connecting part,
A first holding member that is inserted into the first connecting portion across the insertion direction of the connecting member;
A second holding member that is inserted into the second connecting part across the insertion direction of the connecting member;
In the first connecting portion, the connecting member and the first holding member cross each other and engage with each other, so that the connecting member and the first holding member cannot be removed from the first connecting portion, respectively.
In the second connecting portion, the connecting member and the second holding member cross each other and engage with each other, whereby the connecting member and the second holding member cannot be extracted from the second connecting portion, respectively. The gaming machine according to means 1.

  According to the above-described means 2, the connecting member and the holding member cross each other and engage at the first connecting portion and the second connecting portion, respectively, so that they cannot be extracted. For this reason, even if one side of the first connecting part or the second connecting part is destroyed, the connecting member and the holding member cannot be removed from the other side unless the other side is destroyed. As a result, it is possible to further enhance the above-described fraud deterrence effect.

  In addition, as described above, each holding member is “unable to be removed” means that the holding member cannot be removed from the connecting portion unless the first connecting portion or the second connecting portion is destroyed. This means that it is impossible to release the engagement state between the connecting member and the holding member at the connecting portion.

  Means 3. 3. The gaming machine according to claim 2, wherein the insertion direction of the connecting member is orthogonal to the insertion direction of at least one of the first holding member and the second holding member.

  According to the means 3, the connecting member and the holding member are controlled to be orthogonal to each other in the direction in which they are pulled out from each other, so that both of them can be more reliably removed from the connecting portion, and the above-mentioned fraudulent deterrent effect can be further improved. Can be increased.

  Means 4. The gaming machine according to claim 2 or 3, wherein the connecting member and at least one of the first holding member and the second holding member are engaged with each other so as not to be extracted.

  According to the means 4, since the engagement state of the connecting member and the holding member is more stable and cannot be reliably extracted from the connecting portion, it is possible to further enhance the effect of suppressing the fraud. As a configuration example, for example, on the first connecting portion side into which the distal end side of the connecting member is inserted, the rod-like connecting member is inserted into the hole portion of the flat plate-shaped first holding member arranged in advance, and the connecting member A configuration in which the peripheral edge of the hole of the first holding member is fitted to the constricted portion provided in the two and the both are engaged is exemplified. Moreover, in the 2nd connection part side by which the rear end side of a connection member is arrange | positioned, with respect to the constriction part provided in the rod-shaped connection member inserted previously, the flat plate shape notched in the substantially C shape Examples include a configuration in which the distal end portion of the second holding member is fitted and the both are engaged.

  Means 5. In the relationship between the connecting member and at least one of the first holding member and the second holding member, by inserting one of the connecting member or the holding member into the other, a part of the other member is deformed, The game according to means 4, wherein the connecting member and the holding member engage with each other in an unremovable manner when the portion is in a state of restricting movement of one member in the pulling direction as a locking portion. Machine.

  According to the means 5, for example, by inserting a rod-like connecting member into the hole of the flat plate-like holding member, the peripheral edge of the hole of the holding member is irreversibly deformed, and the corresponding portion becomes the locking portion (the locking claw ) And engaging with the constricted portion of the connecting member in a state in which the movement of the connecting member in the pulling-out direction is restricted. As a result, the effect of the means 4 can be further enhanced.

Means 6. The first connecting portion has an insertion hole into which the connecting member is inserted, and a first lateral hole portion provided to intersect with the inserting direction of the connecting member,

In the first connecting portion, the first holding member and the connecting member are crossed and engaged with each other in a state where the first holding member is inserted into the first lateral hole portion,
In the second connecting portion, the second holding member and the connecting member intersect and engage with each other in a state where the second holding member is inserted into the second lateral hole portion. A gaming machine according to any one of means 2 to 5.

  According to the means 6, since the connecting member and the holding member are engaged with each other in a state where the connecting member and the holding member are inserted into the holes (or the holes) having different openings, It becomes difficult to cancel. The “hole” refers to a non-penetrating “recess”, and the “hole” does not include a “hole (hole)” that passes therethrough.

  Mean 7 The connecting member, the first holding member, and the second holding member are accommodated in a state of being flush with a surface of the first connecting portion or the second connecting portion or being recessed from the surface. A gaming machine according to any one of 2 to 6.

  According to the above means 7, since both the connecting member and the holding member are immersed in each connecting portion, for example, a part of the connecting member and the holding member is twisted while being held by a tool or the like. The act of breaking is difficult, and as a result, it is possible to further enhance the deterrent effect.

  Means 8. At least two sealing means are used. In one sealing means, the first connecting portion is provided in the box base and the second connecting portion is provided in the box cover. In the other sealing means, the first connecting portion is provided with the first connecting portion.

  The first opportunity corresponding unit 33 includes an upper winning opening 33a and a lower winning opening 33b, and a pair of opening / closing members 33c corresponding to the lower winning opening 33b. As a result, the upper winning opening 33a is in an open state in which a game ball can always enter, whereas the lower winning opening 33b is opened and closed by the opening / closing member 33c according to the establishment of a predetermined condition. There is a switch between a closed state where the ball cannot enter and an open state where the game ball can enter. For example, the lower winning opening 33b is when the opening / closing member 33c is in the open state in the normal mode and a specified time (for example, 0.2 seconds) elapses or when a specified number (for example, 1) of game balls have entered. Closed. This opening / closing process is performed only once in the normal mode. Instead of the above configuration, the lower winning opening 33b may be switched between a closed state in which a game ball is difficult to enter and an open state in which the game ball is easier to enter than the closed state.

  The variable display device unit 35 receives a prize for the normal symbol display device 41 that variably displays with the passage of the second opportunity corresponding port 34 as a trigger, and the first opportunity corresponding unit 33 (upper winning port 33a or lower winning port 33b). A special display device 43 that performs variable display as a trigger and a decorative symbol display device 42 that performs variable display in accordance with the variable display by the special display device 43 are provided.

  The normal symbol display device 41 is configured so that “O” or “X” can be lit and displayed as a normal symbol, and each time the game ball passes through the second opportunity corresponding port 34, for example, the normal symbol is changed from “O” to “ Switching display (fluctuation display) is performed at high speed such as “×” → “◯” →. When the change display is stopped for a few seconds with the “◯” symbol (winning symbol), the first opportunity corresponding unit 33 is activated for a predetermined time. The display contents of the normal symbol display device 41 are directly controlled by a main control device 261 described later.

  In addition, when the game ball newly passes through the second opportunity corresponding port 34 during the fluctuation display of the normal symbol display device 41, the corresponding fluctuation display is performed after the end of the fluctuation display performed at that time. It is configured to be performed. That is, the variable display is on standby (held). The maximum number of the variable display to be held is determined for each model of the pachinko machine, but in this embodiment, it is held up to 4 times, and the hold number is lit and displayed by the hold lamp 44. Yes.

  The special display device 43 is provided on the right side of the normal symbol display device 41, and is composed of three-color light emitting diodes (three-color LEDs) having red, green, and blue emission colors. Then, each time the game ball wins the first opportunity corresponding unit 33, a color change display (variable display) is performed, and the lighting mode (lighting color) when the variable display stops determines whether or not it is a big hit. Is displayed.

  More specifically, when the game ball wins the first opportunity corresponding unit 33, the special display device 43 displays the three-color LED at a high speed such as red → green → blue → red →. When a predetermined time elapses, it is determined and displayed in one of the colors. High-speed color change display means, for example, that red, green, and blue are displayed in order every 4 msec. In the case of winning the big hit lottery, at this time, it is determined and displayed in red or green (for example, stopped for several seconds), and a special gaming state occurs. In particular, red is a display indicating that the game mode after the jackpot is a high probability mode, and green is a display indicating that the game mode after the jackpot is a time reduction mode. The display content of the special display device 43 is also directly controlled by the main control device 261.

  Further, when a new game ball wins the first opportunity corresponding unit 33 during the variable display of the special display device 43, the corresponding variable display is performed after the end of the variable display at that time. It has a configuration. That is, the variable display is on standby (held). The maximum number of the variable display to be held is determined for each model of the pachinko machine, but in this embodiment, it is held up to 4 times, and the hold number is lit and displayed by the hold lamp 46. Yes. In addition, when a new game ball wins the first opportunity corresponding unit 33 during the big hit state, the corresponding change display is also suspended.

  The decorative symbol display device 42 is configured as a liquid crystal display device, and display contents are controlled by a sub-control device 262 and a display control device 45 described later. That is, in the decorative symbol display device 42, auxiliary display contents are determined by the sub-control device 262 based on a command from the main control device 261 so as to correspond to the result displayed on the special display device 43, Display is performed by the display control device 45. On the decorative symbol display device 42, for example, three symbol rows of upper, middle and lower are displayed. Each symbol sequence is composed of a plurality of symbols, and these symbols are scrolled and displayed on the decorative symbol display device 42 so as to be scrolled for each symbol sequence, and then the upper symbol sequence → the lower symbol sequence → the middle symbol sequence. Stops are displayed in order. The variable display device unit 35 is provided with a center frame 47 so as to surround the decorative symbol display device 42.

  The variable winning device 32 is normally in a closed state in which a game ball cannot be won, and is in an open state in which a game ball can be won in the case of a big hit (occurrence of a special game state). Specifically, the passage of a specified time (for example, 29 seconds) or a specified number (for example, 10) of winnings is regarded as one round (special prize state), and the large winning opening of the variable winning device 32 is repeated a predetermined number of times (a predetermined number of rounds). Opened.

  The game board 30 includes an inner rail constituting part 51 and an outer rail constituting part 52, and a rail 50 for guiding a game ball launched from the launching device 70 to the upper part of the game board 30 is attached. As a result, the game balls fired in accordance with the turning operation of the handle 18 are guided through the launch rail 61 and the rail 50 into a game area formed between the game board 30 and the glass unit 137.

  A return ball preventing member 53 is attached to the tip portion of the inner rail constituting portion 51 (the upper left portion in FIG. 4). This prevents a situation in which the game ball once guided from the rail 50 to the game area returns to the rail 50 again.

  In the present embodiment, the outer rail component 52 is interrupted at the upper right portion of the game board 30, and the inner rail component 51 is interrupted at the lower right portion of the game board 30. For this reason, the game area is defined by the inner peripheral surface of the rail 50 and the window hole 39 of the resin base 38. However, the parallel part of the inner and outer rail components 51 and 52 is excluded.

  As shown in FIG. 3, on the back side of the front frame set 14, a ball passage 71 is provided below the window portion 101 so as to connect to a discharge port 16 of the lower plate 15 from a payout mechanism portion 352 described later. In addition, there is a gap of a predetermined interval between the firing rail 61 provided on the inner frame 12 and the rail 50 (outer rail constituting portion 52), and the game dropped from the gap on the back side of the front frame set 14 A foul ball passage 72 for guiding the ball to the lower plate 15 is formed. Thus, if the game ball launched from the launching device 70 does not reach the return ball prevention member 53 and returns to the rail 50 as a foul ball, the foul ball is transferred to the lower plate 15 via the foul ball passage 72. Discharged.

  3 and 4 is a payout passage for guiding a game ball paid out by a payout mechanism portion 352, which will be described later, to the front of the inner frame 12, a passage leading to the upper plate 19, and a ball passage. 71 and the passage leading to the lower plate 15. A shutter 68 is provided below the payout passage 67. When the front frame set 14 is opened, the shutter 68 protrudes forward by an urging force of a spring or the like so that the outlet of the payout passage 67 is almost closed. ing. When the front frame set 14 is closed, the shutter 68 is pushed open by the rear end portion on the entrance side of the ball passage 71.

  Next, the back configuration of the pachinko machine 10 will be described with reference to FIGS. Various control boards are arranged on the back of the pachinko machine 10 so as to be lined up, down, left and right, and partially overlapped in the front and back, and further, a game ball supply device (payout mechanism) for supplying game balls And a protective cover made of resin. The dispensing mechanism and the protective cover are integrated as one unit, and the resin portion is generally sometimes referred to as a back pack. Therefore, this unit is referred to as a “back pack unit 203”.

  First, the back configuration of the game board 30 will be described. As shown in FIG. 6, on the back side of the variable display device unit 35 (see FIG. 4) arranged corresponding to the through hole in the center of the game board 30, a resin frame cover that covers the center frame 47 from the back side. 213 is provided to protrude rearward. Further, on the back side of the frame cover 213, a decorative symbol display device 42, a display control device 45, and a sub control device 262, which are liquid crystal display devices facing forward from the opening of the frame cover 213, can be attached and detached in a state where they are stacked in front and back. Is attached.

  The decorative symbol display device 42 is housed in a housing box 42 a in which an opening for exposing the display unit (liquid crystal screen) of the decorative symbol display device 42 to the front side of the pachinko machine 10 is formed, and the rear surface of the frame cover 213. It is fixed on the side. The display control device 45 is accommodated in the substrate box 45a and fixed to the back side of the decorative symbol display device 42 (accommodation box 42a). The sub-control device 262 is accommodated in the substrate box 262a and fixed to the back side of the display control device 45 (substrate box 45a). In the frame cover 213, an LED control board for driving LEDs and the like built in the center frame 47 is disposed. The storage box 42a and the substrate boxes 45a and 262a are made of a transparent resin material or the like so that the inside can be visually recognized.

  Under the frame cover 213, a back frame set 215 is attached to the game board 30 so as to cover the general winning opening 31, the variable winning device 32, the first opportunity corresponding unit 33, and the like from behind. The back frame set 215 includes a ball collection mechanism (not shown) for collecting game balls that have won prizes in various winning ports. The game balls collected by the ball collection mechanism are guided to a discharge passage portion 217 described later, and discharged from the discharge chute of the discharge passage portion 217 to the outside of the pachinko machine 10.

  In the present embodiment, the back frame set 215 functions as a mounting base for the main controller 261. More specifically, the board mounting unit 701 on which the main controller 261 is mounted is pivotally supported with respect to the back frame set 215 and can be opened rearward.

  The main controller 261 is accommodated in a substrate box 263 made of a transparent resin material. As shown in the front view (FIG. 7) and the cross-sectional view (FIG. 8), the substrate box 263 includes a box base 263 a that covers the back side and the periphery of the main controller (main substrate) 261, and an opening of the box base 263 a. As a whole, the box cover 263b that covers is formed into a substantially rectangular parallelepiped shape that is long to the left and right. FIG. 8 is a partial cross-sectional view taken along the line KK of FIG. 7, but the appearance of a caulking pin 267 to be described later is shown for convenience (the same applies to other cross-sectional views hereinafter). The main board (main control device) 261 corresponds to the control board in this embodiment. Accordingly, the substrate box 263 corresponds to the substrate box in the present embodiment.

  The box base 263a and the box cover 263b are connected by a sealing unit 264 as sealing means after the main controller 261 is accommodated. By doing so, the substrate box 263 can be sealed.

  Hereinafter, the sealing unit 264 will be described in detail with reference to the drawings. In the present embodiment, a total of eight sealing units 264 are provided, four on each of the left and right sides of the substrate box 263.

  Each sealing unit 264 of the present embodiment includes a caulking pin 267 that serves as a connecting and holding means for a first connecting portion 265 formed on one of the box base 263a or the box cover 263b and a second connecting portion 266 formed on the other. And it will be in a sealing state by connecting using locking piece 268. The caulking pin 267 constitutes a connecting member in the present embodiment, and the locking piece 268 constitutes a first holding member.

  The 1st connection part 265 makes bottomed substantially cylindrical shape provided with the insertion hole 271 in which the crimp pin 267 is inserted. An insertion hole 272 that communicates with the insertion hole 271 is formed through the second connection part 266 that is assembled to the opening side of the first connection part 265. And the crimp pin 267 will be inserted in the insertion hole 271 of the 1st connection part 265 via the insertion hole 272 from the 2nd connection part 266 side.

  However, in the four sealing units 264 (hereinafter referred to as “type A” for convenience) provided on the left side when viewed from the front of the substrate box 263 and the four sealing units 264 (hereinafter referred to as “type B” for convenience) provided on the right side, The direction in which the caulking pin 267 is inserted is different.

  More specifically, in each type A sealing unit 264, the first connecting portion 265 is integrally formed with the box base 263a via the first separating portion 273, and the second connecting portion 266 is interposed via the second separating portion 274. The box cover 263b is integrally formed. On the other hand, in each type B sealing unit 264, the first connecting portion 265 is formed integrally with the box cover 263b via the first separating portion 273, and the second connecting portion 266 is interposed via the second separating portion 274. The box base 263a is integrally formed. Accordingly, in each type A sealing unit 264, the caulking pin 267 is inserted from the front side of the substrate box 263 (box cover 263b side), whereas in each type B sealing unit 264, the back side of the substrate box 263 (box base) The caulking pin 267 is inserted from the 263a side).

  The first separating portion 273 and the second separating portion 274 are formed thinner than the first connecting portion 265 and the second connecting portion 266, respectively, and the connecting portions 265 and 266 come into contact with each other and are in a connected state. Even in some cases, a gap is formed between the two separating portions 273 and 274. By forming this gap, since the cutting edge of a tool such as a nipper can enter the gap when opening the substrate box 263 as will be described later, each of the separation portions 273 and 274 can be easily and individually provided. Can be cut into pieces.

  The connecting portions 265 and 266 and the separating portions 273 and 274 are formed of a resin material, whereas the caulking pins 267 inserted into the sealing unit 264 are formed of a metal material such as a stainless steel material. As shown in FIG. 9, the caulking pin 267 has a cylindrical shaft portion 267a extending along the predetermined axis C1 direction, and a proximal end side (upper side in FIG. 9) of the shaft portion 267a than the shaft portion 267a. And a large-diameter head 267b.

  Further, a fitting groove 267c is formed along the circumferential direction of the shaft portion 267a on the distal end side (lower side in FIG. 9) of the shaft portion 267a in the vicinity of the distal end portion, that is, a position slightly closer to the proximal end side than the distal end portion. Yes. By forming the fitting groove 267c, the tip of the shaft portion 267a becomes a locking portion 267d. A tapered chamfered portion 267e is formed around the distal end side of the locking portion 267d to facilitate insertion into the insertion hole 271 and the like. A portion where the fitting groove 267c is formed constitutes a constricted portion of the caulking pin 267 corresponding to the locking piece 268 (first holding member).

  The locking piece 268 that engages with the caulking pin 267 is formed of a metal material such as a stainless steel material, like the caulking pin 267.

  As shown in FIG. 10, the locking piece 268 in the present embodiment has an oval shape and has a circular hole 268 a into which the distal end portion (locking portion 267 d) of the caulking pin 267 is inserted. The inner diameter of the hole portion 268a is set to be smaller than the outer diameter of the general portion of the shaft portion 267a of the caulking pin 267, and approximately equal to the diameter of the shaft portion 267a where the fitting groove 267c is formed. A plurality of tongue-like pieces 268c are formed on the peripheral edge of the hole 268a by forming a plurality of cuts 268b extending radially from the center of the hole 268a. As a result, the peripheral edge of the hole 268a is easily elastically deformed, and the tip of the caulking pin 267 can be easily inserted.

  The insertion hole 271 of the first connecting portion 265 into which the caulking pin 267 is inserted has a circular cross section, and the inner diameter thereof is set to be substantially the same as the outer diameter of the shaft portion 267a of the caulking pin 267. . Therefore, when the caulking pin 267 is inserted, there is almost no gap between them. However, a slight clearance is provided in consideration of insertion of the caulking pin 267 and the like.

  In addition, the peripheral wall portion of the first connecting portion 265 has a horizontal hole-shaped slit hole 277 that communicates with the insertion hole 271 at a position opposite to the connection position of the first separation portion 273 and the insertion hole 271. It is formed [see FIG. 11 (a) etc.]. The slit hole 277 constitutes a first lateral hole portion corresponding to the locking piece 268 (first holding member) in the present embodiment.

  The slit hole 277 extends perpendicular to the direction of the axis C <b> 2 of the insertion hole 271, passes through the peripheral wall portion of the first connection portion 265, and opens on the outer peripheral surface of the first connection portion 265. Then, the locking piece 268 is inserted into the first connecting portion 265 from the opening of the slit hole 277.

  A groove portion 278 is formed on the inner peripheral wall surface of the insertion hole 271 so as to be engaged with the slit hole 277 so that the peripheral edge portion of the locking piece 268 inserted from the slit hole 277 is locked.

  The slit hole 277 and the groove 278 are formed corresponding to the oval peripheral shape of the locking piece 268, and the locking piece 268 is inserted in the state where the locking piece 268 is inserted into the first connecting portion 265. The whole is housed in the first connecting portion 265.

  The thickness of the slit hole 277 (the width in the direction of the axis C2) is also set to be substantially the same as the thickness of the locking piece 268. When the locking piece 268 is inserted into the slit hole 277, there is almost no gap therebetween. There is no gap and the contact state is established, and the locking piece 268 is fitted.

  With these configurations, the exposed surface of the inserted locking piece 268 is flush with the outer peripheral surface of the first connecting portion 265 or slightly intruded from the outer peripheral surface. If it will be in this state, the position of the hole 268a of the latching piece 268 will overlap with the insertion hole 271 of the 1st connection part 265 along the axis line C2.

  Of the insertion hole 271 of the first connecting portion 265, the portion on the bottom side of the slit hole 277 and the groove portion 278 is a large-diameter hole portion 271a having a larger diameter than the opening side. This is a device for facilitating deformation of the peripheral portion (tongue-like piece 268c) of the hole 268a of the locking piece 268, as will be described later.

  Further, the second connecting portion 266 has a stepped engagement so that the periphery of the insertion hole 272 is notched on the non-contact surface side with the first connecting portion 265, that is, on the side where the caulking pin 267 is inserted. A recess 279 is formed [see FIG. When the caulking pin 267 is inserted, the head 267b of the caulking pin 267 is locked to the bottom of the engagement recess 279, so that the movement of the caulking pin 267 toward the first connecting portion 265 is restricted. In this state, the head 267b of the caulking pin 267 is immersed more than the end surface of the second connecting portion 266 on the non-contact side (see FIG. 11D and the like).

  Next, a procedure for sealing the substrate box 263 by the sealing unit 264 will be described. First, the box cover 263b is assembled to the box base 263a in a state where the main controller 261 is accommodated. More specifically, a plurality of locking portions 285 are formed on the upper side and lower side of the box base 263a so as to protrude in a substantially L shape so that the front end faces rightward when viewed from the front of the substrate box 263. A slit 286 is formed on the upper side and the lower side of the box cover 263b corresponding to each locking portion 285. Then, when assembling, first, the box cover 263b is put on the box base 263a so that the locking portions 285 are inserted into the corresponding slits 286, respectively. Subsequently, the box cover 263b is slid leftward. Thereby, each latching | locking part 285 is latched by the box cover 263b, it will be in the state by which the movement of the box cover 263b to the board | substrate box 263 front side was controlled, and assembly | attachment is completed (refer FIG. 7).

  When the assembly of the board box 263 is completed, as shown in FIG. 11A, the first connecting portion 265 and the second connecting portion 266 constituting each sealing unit 264 come into contact with each other, and the insertion hole 271 and the insertion hole 272 are brought into contact. Will be in communication.

  In this state, the locking piece 268 is inserted into the slit hole 277 of one of the four sealing units 264 of type A (left side) as shown in FIG. Similarly, the locking piece 268 is inserted into the slit hole 277 for one of the four sealing units 264 of type B (right side). FIG. 7 shows a state in which the uppermost one is used in type A and the lowermost one is used in type B. However, the present invention is not limited to this, and at least one each of types A and B is shown. Any combination is possible as long as they are combined and used as one set.

  Subsequently, as shown in FIG. 11B, the caulking pins 267 are respectively inserted into the pair of type A and B sealing units 264 into which the locking pieces 268 are inserted. Again, at this time, in the type A sealing unit 264, the caulking pin 267 is inserted from the box cover 263b side, and in the type B sealing unit 264, the caulking pin 267 is inserted from the box base 263a side.

  When the shaft portion 267a of the caulking pin 267 is inserted into the insertion hole 271 of the first connecting portion 265, the tip of the shaft portion 267a (the locking portion 267d) is the peripheral portion of the hole portion 268a of the locking piece 268. It hits (tongue piece 268c). Further, when the head 267b of the caulking pin 267 is pushed down and the caulking pin 267 is pushed in, the locking portion 267d of the caulking pin 267 elastically moves the peripheral portion (tongue-like piece 268c) of the hole 268a of the locking piece 268. While being deformed (see FIG. 11C), it penetrates into the insertion hole 271 and is accommodated in the large-diameter hole 271a (see FIG. 11D). Since the large-diameter hole portion 271a is formed, on the bottom side of the insertion hole 271, there are few portions that support the tongue-like piece 268c of the locking piece 268. Therefore, the tongue-like piece 268c is inserted into the insertion hole 271. It becomes easy to bend to the bottom side. In other words, the tongue-like piece 268c is unlikely to bend toward the opening side of the insertion hole 271 due to the step between the general portion of the insertion hole 271 and the large-diameter hole portion 271a. Therefore, as will be described later, in the state where the tongue-like piece 268c is engaged with the locking portion 267d of the caulking pin 267 as the locking claw (locking portion), the caulking pin 267 is more reliably prevented from coming off. It will be.

  As shown in FIG. 11D, when the locking portion 267d of the caulking pin 267 penetrates the hole 268a of the locking piece 268, the tongue-like piece 268c at the periphery of the hole 268a is restored, so that the caulking pin 267 is fitted into the fitting groove 267c. As a result, both the caulking pin 267 and the locking piece 268 are in a state where they cannot be removed. However, the tongue-like piece 268c at the periphery of the hole 268a is not completely restored, is slightly curved toward the bottom side of the insertion hole 271, and is a locking claw (engagement) that locks the locking portion 267d of the caulking pin 267. To play a role. Similarly, the head 267b of the caulking pin 267 is locked to the bottom of the engaging recess 279 of the second connecting portion 266, so that the movement of the caulking pin 267 toward the first connecting portion 265 is restricted. Is done.

  Finally, as shown in FIG. 11D and the like, the blocking portion 300 is formed by pouring a resin material such as an ultraviolet curable resin into the engaging recess 279 of the second connecting portion 266 and curing it. To do. As a result, the caulking pin 267 cannot be removed from the second connecting portion 266.

  Thus, when the 1st connection part 265 and the 2nd connection part 266 will be in a connection state, the board | substrate box 263 will become unopenable and sealing will be completed.

  Next, a procedure for opening the substrate box 263 in the sealed state when the main controller 261 is taken out from the substrate box 263 for inspection or when the failed main controller 261 is replaced will be described.

  In order to open the substrate box 263, it is necessary to cut the sealing unit 264 being used from the substrate box 263 with a tool such as a nipper.

  Of course, in the sealing unit 264 being used, the substrate box 263 can be opened by cutting both the first separation part 273 and the second separation part 274 and completely removing the used sealing unit 264. However, in this case, the used sealing unit 264 does not remain, and the trace of opening the substrate box 263 becomes inconspicuous.

  In addition, in this embodiment, when opening the substrate box 263, the box cover 263b must be slid once to the right and removed, contrary to the assembly procedure. Therefore, depending on how to cut, the used sealing unit 264 may interfere with the sliding of the box cover 263b.

  For the above reasons, in this embodiment, the substrate box 263 is opened by the following method. First, as shown in FIG. 12, in the type A sealing unit 264, the second separating portion 274 connected to the box cover 263b is cut (see the cutting line H1), and in the type B sealing unit 264, The second separation part 274 connected to the box base 263a is cut (see the cutting line H2). By doing so, the sealing of the substrate box 263 is released, and the box cover 263b can be slid rightward from the box base 263a and removed as shown in FIG.

  Temporarily, contrary to the above configuration (first cutting pattern cut along cutting lines H1 and H2), in type A sealing unit 264, first separating portion 273 connected to box base 263a is cut and type In the B sealing unit 264, when the first separation portion 273 formed to be connected to the box cover 263b is cut (second cutting pattern), the used sealing unit 264 prevents the box cover 263b from sliding, The box cover 263b cannot be removed from the box base 263a.

  Similarly, when the first separation part 273 is cut in the type A sealing unit 264 and the second separation part 274 is cut in the type B sealing unit 264 (third cutting pattern), or the type A sealing unit When the second separation part 274 is cut at H.264 and the first separation part 273 is cut at the type B sealing unit 264 (fourth cutting pattern), the used sealing unit 264 is not used for sliding the box cover 263b. As a result, the box cover 263b cannot be removed from the box base 263a.

  However, this is because the present embodiment has a configuration in which the box cover 263b is slid and attached to and detached from the box base 263a, and both are mounted on the board surface of the main controller (main board) 261. Can be opened by any of the first to fourth cutting patterns as long as it is mounted and removed by moving in a direction perpendicular to the vertical direction (vertical direction in FIG. 12).

  With the above configuration, when the substrate box 263 is opened (including the case where both the first separating portion 273 and the second separating portion 274 are cut and the sealing unit 264 is completely removed) You can leave a history. If the opening history of the board box 263 is left in the board box 263, it is possible to easily find out whether or not unauthorized opening has been performed by looking at the board box 263. Therefore, unauthorized opening after sealing can be prevented, and even if unauthorized opening is performed, such a situation can be detected early and easily. As described above, when both the first separating portion 273 and the second separating portion 274 are cut and the used sealing unit 264 is completely removed, the used sealing unit 264 remains. However, the trace of opening the substrate box 263 becomes inconspicuous, but the trace does not remain. That is, when the sealing unit 264 is completely excised, a trace that the separation parts 273 and 274 are cut by a tool or a history that the sealing unit 264 has disappeared remains, so that it is possible to easily detect an illegal act.

  In this embodiment, since four sets of four each of type A and B sealing units 264 are provided, the unused portions even after the separation portions 273 and 274 are cut and the substrate box 263 is once opened. By newly inserting the caulking pin 267 and the locking piece 268 into the sealing unit 264 (the first connecting portion 265 and the second connecting portion 266) and forming the closing portion 300, the sealing process is performed up to the remaining three times. Is possible.

  Now, the game board 30 corresponds to various winning ports such as a general winning port 31 as a winning means and detects a game ball that has entered the various winning holes (entrance detecting means). Is provided. Specifically, as shown in FIG. 4, a winning opening switch 221 is provided at a position corresponding to the general winning opening 31, and a count switch 223 is provided in the variable winning device 32. The first opportunity corresponding unit 33 is provided with first opportunity corresponding unit switches 224a and 224b corresponding to the upper winning opening 33a and the lower winning opening 33b, respectively. Further, a second opportunity corresponding port switch 225 is provided at a position corresponding to the second opportunity corresponding port 34.

  Although not shown, the back frame set 215 is provided with a first board surface relay board that is electrically connected to the prize opening switch 221, the count switch 223, and the second opportunity corresponding port switch 225 via a cable connector. It has been. The first board surface relay board relays the prize opening switch 221 and the like and the main control device 261 as control means, and is electrically connected to the main control device 261 through a cable connector.

  On the other hand, the first opportunity corresponding switches 224a and 224b that detect the entry into the first opportunity corresponding unit 33 (the upper winning opening 33a or the lower winning opening 33b) are directly connected via the connector cable without passing through the relay board. It is connected to the control device 261.

In a state where the caulking pin 267 is inserted and the head 267b is immersed in the engaging recess 279, there is almost no gap between the outer peripheral portion of the head 267b of the caulking pin 267 and the inner peripheral wall portion of the engaging recess 279. It is not formed. However, a slight clearance is provided in consideration of insertion of the caulking pin 267 and the like.

  Furthermore, a second fitting groove 267f is formed along the circumferential direction of the shaft portion 267a at the boundary portion between the head portion 267b of the caulking pin 267 and the shaft portion 267a. By forming the second fitting groove 267f, the portion becomes a narrow neck portion 267g. And the 2nd latching piece 290 shown in FIG. 18 is fitted by the said neck part 267g. The second locking piece 290 corresponds to the second holding member in the present embodiment. Therefore, the neck portion 267g of the caulking pin 267 constitutes a constricted portion corresponding to the second holding member.

  Like the locking piece 268, the second locking piece 290 is formed in a small size by a metal material. The second locking piece 290 is formed with a fitting recess 290a that fits into the neck 267g of the caulking pin 267 so that a part of the peripheral edge is cut away. The fitting recess 290a has an opening narrower than the back side so as to prevent the caulking pin 267 from falling off the neck 267g. This shape substantially matches the cross-sectional shape of the neck portion 267g of the caulking pin 267. As a result, the fitting recess 290a is fitted to the neck 267g of the caulking pin 267 with almost no gap.

  In addition, a lateral slit-shaped slit hole 293 that communicates with the insertion hole 272 is formed in the peripheral wall portion of the second connection portion 266 at a position that is opposite to the connection position of the second separation portion 274 and the insertion hole 272. [Refer to FIG. 19 (a) etc.]. The slit hole 293 constitutes a second lateral hole portion corresponding to the second locking piece 290 (second holding member).

  The slit hole 293 extends perpendicular to the direction of the axis C <b> 2 of the insertion hole 272, passes through the peripheral wall portion of the second connection portion 266, and opens on the outer peripheral surface of the second connection portion 266. Then, the second locking piece 290 is inserted into the second connecting portion 266 from the opening of the slit hole 293.

  The slit hole 293 is formed corresponding to the oval peripheral shape of the second locking piece 290, and in the state where the second locking piece 290 is inserted into the second connecting portion 266, the second hole The entire locking piece 290 is accommodated in the second connecting portion 266.

  The thickness of the slit hole 293 (width in the direction of the axis C2) is also set to be substantially the same as the thickness of the second locking piece 290, and in the state where the second locking piece 290 is inserted into the slit hole 293, , There is almost no gap between them, and a contact state is established, and the second locking piece 290 is fitted.

  With these configurations, the exposed surface of the inserted second locking piece 290 is in a state of being flush with the outer peripheral surface of the second connecting portion 266 or slightly more than the outer peripheral surface. If it will be in this state, the position of the fitting recessed part 290a of the 2nd locking piece 290 will overlap with the penetration hole 272 of the 2nd connection part 266, and the axis line C2.

  Next, a procedure for sealing the substrate box 263 by the sealing unit 264 in this embodiment will be described. First, the box cover 263b is assembled to the box base 263a in a state where the main controller 261 is accommodated. In the present embodiment, the box cover 263b is moved and attached in a direction orthogonal to the substrate surface of the main controller (main substrate) 261 to be attached and removed.

  When the assembly of the board box 263 is completed, as shown in FIG. 19A, the first connecting portion 265 and the second connecting portion 266 constituting each sealing unit 264 come into contact with each other, and the insertion hole 271 and the insertion hole 272 are brought into contact with each other. Will be in communication.

  In this state, as in the first embodiment, each of the four sealing units 264 of type A (left side) and type B (right side) has a slit hole as shown in FIG. After inserting the locking piece 268 into 277, the caulking pin 267 is inserted.

  When the shaft portion 267a of the caulking pin 267 is inserted into the insertion hole 271 of the first connecting portion 265, the locking portion 267d of the caulking pin 267 is moved to the peripheral portion (tongue-like shape) of the hole portion 268a of the locking piece 268. The piece 268c) is elastically deformed (see FIG. 19B), penetrates into the insertion hole 271 and is accommodated in the large-diameter hole portion 271a (see FIG. 19C). At the same time, the tongue-like piece 268c at the periphery of the hole 268a is restored and fitted into the fitting groove 267c of the caulking pin 267. As a result, both the caulking pin 267 and the locking piece 268 are in a state where they cannot be removed. In the same manner, the head 267 b of the caulking pin 267 is immersed in the engaging recess 279 of the second connecting portion 266.

  Subsequently, as shown in FIG. 19C, the second locking piece 290 is inserted into the slit hole 293 with the fitting recess 290a at the head. As the second locking piece 290 is inserted, the insertion-side tip of the second locking piece 290 hits the neck 267g of the caulking pin 267. Further, when the second locking piece 290 is pushed in, the neck 267g of the caulking pin 267 is elastically deformed so that the narrow opening of the fitting recess 290a is widened. When this portion passes the neck portion 267g, the tip end portion of the second locking piece 290 is restored, and the second locking piece 290 is fitted to the neck portion 267g of the caulking pin 267 (see FIG. 19D). Thereby, both the caulking pin 267 and the second locking piece 290 are in a state in which they cannot be removed.

  Thus, when the 1st connection part 265 and the 2nd connection part 266 will be in a connection state, the board | substrate box 263 will become unopenable and sealing will be completed.

  In the present embodiment, the substrate box 263 can be opened by any of the first to fourth cutting patterns described in the first embodiment.

  By doing in this way, the effect similar to the said embodiment is show | played. In addition, this embodiment is superior in terms of workability compared to the first embodiment because the operation of embedding the caulking pin 267 with a resin material is not required in the second connecting portion 266.

  In addition, it is not limited to the description content of embodiment mentioned above, For example, you may implement as follows.

  (A) In the above embodiment, the present invention is applied to the sealing configuration for sealing the substrate box 263 containing the main control device 261. However, the present invention is not limited to this, and of course the substrate box 311a of the dispensing control device 311 is used. Of course, the present invention may be applied to other board boxes such as a board box 262a that houses the sub-control device 262.

  (B) The number and configuration of the sealing units 264 are not limited to the above embodiment. For example, in the above-described embodiment, the first connecting portion 265 is configured such that the caulking pin 267 is inserted after the locking piece 268 is inserted and the both engage with each other. As in the relationship with the second locking piece 290, the locking piece 268 may be inserted after the caulking pin 267 is inserted, and both may be engaged. Similarly, in the second connecting portion 266, the caulking pin 267 may be inserted after the second locking piece 290 is inserted, and both may be engaged.

  In addition, a through hole having a horizontal hole is formed in the shaft portion 267a of the caulking pin 267, and a return pin or the like used as a holding member is inserted into the through hole so that the two intersect with each other. Thereby, it is good also as a structure which cannot be extracted from the 1st connection part 265 or the 2nd connection part 266.

  As a specific example, a substantially plate-like connecting member 800 as shown in FIG. 20 may be used instead of the substantially bar-shaped caulking pin 267 of each of the above embodiments. Hereinafter, this embodiment will be described with reference to FIGS. However, the same components as those in the above embodiments are given the same reference numerals, and detailed descriptions thereof are omitted.

  The connecting member 800 used in the sealing unit 264 of the present embodiment is formed of a metal material, like the caulking pin 267 of each of the above embodiments. As shown in FIG. 20, the connecting member 800 has a rectangular shape, and slit holes 800 c into which holding pins 850 as holding members are inserted are formed at two locations in the longitudinal direction.

  The holding pin 850 is made of a metal material, and has a substantially flat plate portion 850a inserted into the first connecting portion 265 or the second connecting portion 266, and is integrally formed with the first connecting portion 265 or And a head portion 850b engaged with the second connecting portion 266, and has a substantially T shape in front view. More specifically, the flat plate portion 850a has a rectangular shape, and the head portion 850b is formed in a cylindrical shape so that one end side in the longitudinal direction of the flat plate portion 850a is wound. Then, in the vicinity of the tip of the flat plate portion 850a on the side opposite to the head portion 850b, a part of the flat plate portion 850a is cut out in a U-shape, thereby forming two locking claws 850c having the head portion 850b side as a free end. Has been. These locking claws 850c protrude from the front and back surfaces of the flat plate portion 850a by bending the free end sides in opposite directions. Of the holding pins 850, the one inserted into the first connecting portion 265 corresponds to the first holding member in the present embodiment, and the one inserted into the second connecting portion 266 corresponds to the second holding member.

  In the present embodiment, the internal structures of the first connecting portion 265 and the second connecting portion 266 that constitute the sealing unit 264 are also different from the above-described embodiments in accordance with the configurations of the connecting member 800 and the holding pin 850. Different changes have been made.

  For example, the insertion hole 271 of the first connection part 265 and the insertion hole 272 of the second connection part 266 are both formed in a relatively narrow cross-sectional rectangular shape (slit shape) in accordance with the connection member 800. Yes. In addition, the engagement concave portion 279 of the second connecting portion 266 is also omitted in accordance with the omission of the head and the like. As a result, when the connecting member 800 is inserted into the sealing unit 264 and is immersed, almost no gap is formed between the connecting member 800 and the insertion hole 271 and the insertion hole 272.

  Further, on the opening side of the slit holes 277 and 293 of the first connecting part 265 and the second connecting part 266 into which the holding pin 850 is inserted, there are stepped engaging concave parts 277a and 293a so that the periphery thereof is cut out. Is formed. When the holding pin 850 is inserted, the head 850b of the holding pin 850 is engaged with the engaging recesses 277a and 293a in an immersive state.

  On the inner peripheral wall surface of the insertion hole 271 that faces the slit hole 277 and the inner peripheral wall surface of the insertion hole 272 that faces the slit hole 293, the housing recesses 277b and 293b that respectively accommodate the tip portions of the holding pins 850 are accommodated. Is formed.

  As a sealing procedure, first, as shown in FIG. 21A, the connecting member 800 is inserted into the insertion hole 271 of the first connection portion 265 and the insertion hole 272 of the second connection portion 266 that are in the communication state. Then, as shown in FIG. 21B, the connecting member 800 is accommodated in a state of being immersed in the sealing unit 264. In this state, the slit holes 800c of the connecting member 800 are overlapped with the extension lines of the slit holes 277 of the first connecting portion 265 and the slit holes 293 of the second connecting portion 266, respectively.

  Subsequently, as shown in FIG. 21B, the holding pin 850 is inserted into the slit hole 277 of the first connecting portion 265. When the holding pin 850 is pushed in, both the locking claws 850c are elastically deformed, and the holding pin 850 is inserted into the slit hole 277. When both the locking claws 850 c of the holding pin 850 pass through the slit hole 800 c of the connecting member 800, both the locking claws 850 c are elastically restored and received in the receiving recess 277 b and are locked by the connecting member 800. [See FIG. 21 (c)]. At the same time, the head 850b of the holding pin 850 is engaged with the engaging recess 277a of the first connecting portion 265 in an immersive state. As a result, both the connecting member 800 and the holding pin 850 cannot be removed at the first connecting portion 265. However, in this embodiment, the connecting member 800 and the holding pin 850 are not detachably engaged with each other, and both of them can be extracted, but are accommodated in the first connecting portion 265, and both When the engagement state is not released, the state becomes impossible to extract.

  Similarly, as shown in FIG. 21C, the holding pin 850 is inserted into the slit hole 293 of the second connecting portion 266. When the holding pin 850 is pushed in, both the locking claws 850c are elastically deformed, and the holding pin 850 is inserted into the slit hole 293. When both the locking claws 850c of the holding pin 850 pass through the slit hole 800c of the connecting member 800, the both locking claws 850c are elastically restored and received in the receiving recess 293b, and are locked by the connecting member 800. [See FIG. 21 (d)]. At the same time, the head portion 850b of the holding pin 850 is engaged in an engaged state with the engagement recess 293a of the second connecting portion 266. As a result, both the connecting member 800 and the holding pin 850 are in a state in which they cannot be removed at the second connecting portion 266. However, similarly to the above, the connecting member 800 and the holding pin 850 are not engaged with each other so as not to be extracted, and both can be extracted but are accommodated in the second connecting portion 266 and both When the engagement state is not released, the state becomes impossible to extract.

  Thus, when the 1st connection part 265 and the 2nd connection part 266 will be in a connection state, the board | substrate box 263 will become unopenable and sealing will be completed.

  (C) In each of the above embodiments, a configuration in which the connecting member such as the caulking pin 267 is locked by the holding member such as the locking piece 268 is described, but the holding member such as the locking piece 268 is omitted. It is good.

  As a specific example, there is an example in which a caulking pin 870 having a substantially plate-like body as shown in FIG. 22 is used instead of the caulking pin 267 having a substantially rod-like body in each of the above embodiments. Hereinafter, this embodiment will be described with reference to FIGS. However, the same components as those in the above embodiments are given the same reference numerals, and detailed descriptions thereof are omitted.

  The caulking pin 870 as a connecting member used in the sealing unit 264 of the present embodiment is almost the same except that it includes two sets of locking claws locked to the first connecting portion 265 and the second connecting portion 266. The configuration is the same as that of the holding pin 850 in the embodiment described in (b) above. That is, as shown in FIG. 22, the caulking pin 870 includes a substantially flat plate portion 870 a inserted into the first connection portion 265 and the second connection portion 266, a head portion 800 b formed integrally therewith, A set of locking claws 870c provided near the tip of the flat plate portion 870a on the opposite side of the head 800b, and a set of locking claws 870d provided closer to the head 870b. ing.

  Also in the present embodiment, the internal structure and the like of the first connecting portion 265 and the second connecting portion 266 are changed in accordance with the configuration of the caulking pin 870. For example, the slit holes 277 and 293 are omitted in the first connecting portion 265 and the second connecting portion 266, and both engagements on the bottom side of the insertion hole 271 of the first connecting portion 265 are fixed on the tip side of the caulking pin 870. A storage chamber 861 in which the claw 870c is stored is formed, and a storage chamber 863 in which both the locking claw 870d on the head 870b side is stored is formed in the middle of the insertion hole 272 of the second connecting portion 266. . Further, the shape of the engaging recess 279 of the second connecting portion 266 is also set according to the shape of the head 870b of the caulking pin 870, and the caulking pin 870 is inserted into the sealing unit 264, and the head 870b is engaged. In the state of being immersed in the joint recess 279, almost no gap is formed between the head 870b and the side wall of the engagement recess 279.

  As a sealing procedure, first, as shown in FIG. 23A, the caulking pin 870 is inserted into the insertion hole 271 of the first connection part 265 and the insertion hole 272 of the second connection part 266 that are in a communication state. . When the caulking pin 870 is pushed in, first, both locking claws 870c on the distal end side are inserted into the insertion hole 272 while being elastically deformed. Subsequently, when both the locking claws 870c on the distal end side are inserted into the insertion hole 271, both the locking claws 870d on the head 870b side are inserted into the insertion hole 272 while being elastically deformed. Then, as shown in FIG. 23B, when both the locking claws 870c on the distal end reach the storage chamber 861, the both locking claws 870c are elastically restored and locked to the wall surface of the storage chamber 861. It will be in the state. At the same time, both locking claws 870 d on the head 870 b side reach the storage chamber 863, so that both locking claws 870 d are also elastically restored and locked to the wall surface of the storage chamber 863. In this state, the head portion 870 b of the caulking pin 870 is also engaged in the state where it is immersed in the engaging recess 279 of the second connecting portion 266. As a result, the operation of releasing the locked state of the two sets of locking claws 870c and 870d cannot be performed, and the caulking pin 870 cannot be removed from the first connecting portion 265 and the second connecting portion 266, respectively.

  Thus, when the 1st connection part 265 and the 2nd connection part 266 will be in a connection state, the board | substrate box 263 will become unopenable and sealing will be completed.

  Further, in addition to such a configuration, for example, as shown in FIG. 24, the slit holes 277 and 293 are not omitted in the first connecting portion 265 and the second connecting portion 266 so as to communicate with the storage chambers 861 and 863. 2, after completion of the locking of the caulking pin 870, a resin material 864 such as an ultraviolet curable resin is poured into the storage chambers 861 and 863 through the slit holes 277 and 293, and is cured. If the locking state of the pawls 870c and 870d is made unreleasable, the caulking pin 870 cannot be more reliably extracted from the first connecting portion 265 and the second connecting portion 266. However, the configuration using the holding member such as the locking piece 268 as in the above embodiment is preferable in terms of workability because the operation of pouring the resin material 864 and the like is not required.

  (D) In the above embodiment, in each type A sealing unit 264, the first connecting portion 265 is formed on the box base 263a, and the second connecting portion 266 is formed on the box cover 263b. On the other hand, in each type B sealing unit 264, the first connecting portion 265 is formed on the box cover 263b, and the second connecting portion 266 is formed on the box base 263a. That is, the direction in which the caulking pin 267 is inserted is different. Not only this but the sealing unit 264 of both type A and B used by 1 set is good also as a structure where the direction which inserts the crimp pin 267 is the same. That is, both the type A and B sealing units 264 may have a configuration in which the first connecting portion 265 is formed on the box base 263a and the second connecting portion 266 is formed on the box cover 263b. Alternatively, both the type A and B sealing units 264 may be configured such that the first connecting portion 265 is formed on the box cover 263b and the second connecting portion 266 is formed on the box base 263a.

  In addition, it is not necessary to use two sealing units 264 as a set, and even when only one sealing unit 264 is used, there are sufficient effects to solve the above problems. Even if the sealing units 264 of both types A and B are not necessarily used in one set, if one sealing unit 264 of the present invention is used, one of the box base 263a and the box cover 263b can be left without leaving any trace of opening. Since it cannot be obtained without being damaged, an illegal act such as replacement of the entire board box 263 described above can be suppressed. Of course, it is more preferable to use a pair of sealing units 264 of both types A and B, since both the box base 263a and the box cover 263b can leave traces of opening.

  (E) In the above embodiment, four sealing units 264 are provided on each of the left and right sides of the substrate box 263. The arrangement of the sealing unit 264 is not limited to this. For example, the type A and B sealing units 264 may be provided on the upper side of the substrate box 263 one by one.

  (F) In the above embodiment, a metal member is used as the connecting member such as the caulking pin 267 and the holding member such as the locking piece 268, but the material of the connecting member and the holding member is limited to this. For example, other relatively hard materials such as ceramic and hard resin may be used.

  (G) In the first embodiment, as shown in FIG. 25, a plurality of locking portions formed in a substantially L-shape projecting from the upper side and the lower side of the box base 263a so that the tip faces rightward. 285 is formed, and slits 286 are formed on the upper side and lower side of the box cover 263b corresponding to the respective locking portions 285. Then, when assembling, first, the box cover 263b is put on the box base 263a so that the locking portions 285 are inserted into the corresponding slits 286, respectively. Subsequently, the box cover 263b is slid leftward. Thereby, each latching | locking part 285 is latched by the box cover 263b, and an assembly | attachment is completed. Here, when the assembly is completed, each locking portion 285 is exposed on the front surface of the box cover 263b. From the viewpoint of preventing fraud, each locking portion 285 is locked in the box cover 263b. It is preferable that each of the locking portions 285 is covered so as not to be exposed to the outside.

  On the other hand, in the second embodiment, the box cover 263b is moved and attached in a direction orthogonal to the substrate surface of the main controller (main substrate) 261 to be attached and removed. However, when the box base 263a and the box cover 263b are attached and removed in this way in parallel with the insertion direction of the connecting member such as the caulking pin 267, the board box 263 is not completely opened. 263 may be forcibly opened, and there is a risk that fraudulent acts may be performed inside the gap. Therefore, from the viewpoint of preventing fraud, the slide type in which the box base 263a and the box cover 263b are assembled so as to intersect the insertion direction of the connecting member such as the caulking pin 267 as in the first embodiment. preferable. More preferably, a larger slide amount is required for attachment and removal. For example, there are specific examples as shown below. In the configuration shown in FIG. 26, guide rails 263g are provided on the upper side and the lower side of the box base 263a, and the flanges 263f on both upper and lower edges of the box cover 263b are fitted inside the guide rail 263g. Thus, the box base 263a and the box cover 263b are attached and removed by sliding along the guide rail 263g. In this case, the main control device (main board) 261 is attached to the box cover 263b side in consideration of protrusions of connector terminals and the like which are omitted in the drawing.

  (H) In the above-described embodiment, the insertion direction of the connecting member such as the caulking pin 267 and the insertion direction of the holding member such as the locking piece 268 are orthogonal to each other. It may not be engaged. For example, it is good also as a structure engaged in the state which the holding member inclined with respect to the connection member.

  (I) You may implement as a pachinko machine of a different type from the said embodiment. In addition to pachinko machines, the game is implemented as an arrangement ball machine, various types of game machines such as sparrow balls, slotted machines such as slot machines, and a game machine that combines slot machines and pachinko machines. Also good.
